AVA and Combat Arms are semi-realistic shooters. I've tried to like semi-realistic shooters--really, I have--but I just can't. I own copies of Counter-Strike: Source and Day of Defeat: Source. I can only play CS: S for about 30 minutes at a time and I uninstalled DoD: S the other day after realizing everyone still playing the game is better at it than me and getting steamrolled on pub servers just isn't fun.
Ah, makes since, I like semi-realistic shooters...but I have to agree TF2 is a blast!
Cross Fire is somewhat arcade-y, but even a glimpse at a trailer for Cross Fire makes it obvious that I'd rather fire up Quake Live for a quick lunchtime match. After all, how likely is it that two free games include the best rocket launcher in FPS history?
Honestly, I would play QL over CF, if QL had a pointless leveling system XD...
In other words: No, I haven't played the three other games. But I don't need to. I've watched the other games in action and I already know that I like Quake Live best. When you've been playing PC games as long as I have, it's not unreasonable to decide whether or not you'll enjoy a game (whether it's great or not; I'm talking about personal preference here) from a gameplay video.
I agree with you completely here, if I were not laid off at the moment I would much prefer watching gameplay videos over downloading and trying out a game...
When games are free (or, in the case of Steam sales, incredibly cheap), the deciding resource isn't money, but rather time. True, it may not cost me any money to try out all the other games you mentioned in your poll, but it will cost me time. That's why free games aren't as popular as people expect them to be.
People pay money for retail games like Team Fortress 2; they see the game as more valuable than a free game (like Quake Live) because of the monetary investment. It's the reason why Guild Wars players tend to branch out to other games with greater frequency and less resistance than WoW players. WoW players want to feel like they're getting their $15 worth, so they're less likely to play or buy other games than the average gamer who doesn't play WoW.
One of the reasons I got away from WoW is feeling like I HAD to play because I was paying...not playing because I WANTED to play...
I'd like to write out a full-fledged article on the effect of piracy and Steam sales (no cost or low-cost games) and how the shift in primary expense from money to time expense affects gamers and game selection.
Not sure if this pertains to this but, I read an interview of a championship gamer from Korea the other day, and he said EVERYONE in Korea pirates games instead of buying them...one reason is because they cannot afford them...
