Not that it entirely matters who specifically brought Chess into the conversation, but unless I'm missing an earlier post Lorfa brought it up in reference to armor/health on the map and how it gives an advantage to the player to get it. From that portion of the conversation, it appeared that you were complaining about how it's unfair when players get powerups/pickups/whatever term you want to use and then the game becomes unbalanced.
This is exactly the purpose of them in the game, and they are there to assist the player when they get them. They're intended to imbalance the game and give a single player an advantage; that's the entire reasoning behind them often being in the middle. They're meant to be contested and fought over for the advantage they provide. It provides a common meeting area that is supposed to regulate the gameplay so it doesn't end up just camping the entire time.
Your argument in relation to chess was essentially that Chess is a simple game to learn at the basic level, but at high levels, can be extremely skillful. You could've ended that post saying that QL was the same way, but instead you threw in another thought about how headshots would add more depth to the game (Which is debatable -- I'll include a portion at the end of this post on the reasoning behind this) and that you found that just walking over powerups gave that specific player a huge advantage.
However, as I just stated, the powerups are meant to give an advantage to the player that gets them; that's why they're fought over. This generally gives the assumption to any reader that you're of a lower skill due to the fact that any higher-skilled player would understand that the powerups are supposed to be fought over and generally will become the primary objective when they're about to spawn. (In CTF this is demonstrated by the Offense players staying in mid instead of pushing the base in order to actually get the Quad/Regen)
You then ended your post by saying that you should leave Quake the same, but make a "spiritual successor". So in other words you've contradicted yourself by basically saying "I want a new game but I'm offering suggestions on how to 'improve' QL". This would not be a spiritual successor. This would be a modified version of Quake Live that would not be the same. It's similar to how PQL is supposed to be the QL equivalent of CPMA in Q3. They're not the same, but they're similar. However, most people will probably tell you that CPMA is the better of the two. (I personally disagree, but that's probably because I started with QL and not Q3)
In Lorfa's next post, he brings up a point about where you said that walking over an item makes the game casual. Lorfa's point about Clan Arena was basically that since it is without weapons or anything on the map, it essentially diverges the gameplay completely into casual territory. Without any objectives other than "kill your opponents", there's nothing that forces the players to work together. Powerups are the answer to this as previously stated.
In your next post, you basically said "I don't want headshots" which I don't fully understand because the incorrect grammar made it confusing. You then tell Limbless_Pony that there needs to be more skill involved in using the powerups outside of picking them up. Do you want players to enter a code to activate them or something? This would slow gameplay down immensely. (Yes, I know that's probably not what you meant, but it's not entirely clear since there was nothing specific about it from you. You were vague about the entire thing.)
You then talk about "core gameplay". In this post you are confusing gameplay with mechanics. The gameplay in QL (For Clan Arena) is to kill without being killed. The mechanics in QL are "strafing", "shooting", and "jumping".
We then got to the 'clarification' portion of the thread, which is still going on. We also made fun of Clan Arena's simpleness and talked about Warsow for a short period of time.
Then came the hitmarker conversation. As it appears, you said that hitmarkers take skill out of the game. I then clarified that if you didn't know if you hit your opponent, you wouldn't know their approximate health and therefore wouldn't use an optimal weapon in the correct situation; you'd use the one you're best with all the time, which then makes the game simpler. Then we had a conversation about your skill level, and now I'm going to go into the detail about my opinion of headshots in QL as said I would.
In Quake Live, the gameplay is fast. It's so fast that most of the time you can't even determine the exact location of a player's head while they're strafing around the map. Adding headshots into the game gives what would essentially turn into "aim higher and hope for the best". While this could be extremely beneficial for players who somehow got good enough to get that precise with their shooting, it'd add a completely random element to the game.
Tribes Ascend is a game that has headshots enabled (and it's also fast), yet headshots are so rare to get simply because of how impossible they actually are to get. However, the game does not have additional damage for actually getting a headshot simply because it often is random, and probably because it doesn't want to encourage people to waste attempting to get headshots and miss a lot. It slows the game down when it's purposeful. However, in Call of Duty games, headshots are enabled and because the speed of the movement is slower, it makes perfect sense to have it since it's more obtainable (The damage is 1.4x normal with a headshot in CoD in most games).
EDIT: Screw you all for posting while I wrote this all up :P
The only reason I linked to the Wikipedia page was because it gives an exact definition of all 3 categories and they're all short, together, and to the point.
If you're going to suggest something, you need to be clear with what you mean. Even though IonicAftershock may have guessed what TacticalBurst was thinking, that doesn't mean that everyone else reading the post will get that from it. You have to be as clear as possible so more people understand it. I'm also noticing that TacticalBurst is taking things off-topic now and just appears to be slamming the gaming community as a whole. (Again, I'm assuming because he has nothing to back up anything he's been saying in an exact manner)
