I've played all the MMO's, there's no feature that matters except gameplay. I found TR to be surprisingly fun.
FPS??? ---- TR is not a FPS. It's an MMO with a unique gameplay interface that gives it the feel of a shooter while your leveling and growing your character. People who love FPS are complaining that TR is not a real FPS (who lied to you about that?); and people who love MMO's are a little bewildered by the fast paced, shooter action. I'll I have to say is, "Thank God someone decided to do something different with MMO gameplay than the one button stand and fight." It's very addictive running around with your rifle and smoking aliens. If you're like me and tried to play the game like WoW/EQ, where you run up and stand and fight, you will quickly find this to be sub-optimal on the ranged battlefield. The equivalent to having many abilities/spells is switching weapon types and using Logos powers; you need to move, duck, find cover, reload, move more, get position, fight, kill move on... I still see tons of people never doing this... it takes a rethinking for the MMO crowd to catch on to this, and because of it I suspect many will go back to their one-button warriors and warlocks.
So what about WoW??? --- I've heard the normal group of idiots on the General channel yelling - "WoW is better!". I think this is accurate if you change it to - "WoW was better." Now, WoW is just OLD. I mean, face it... the game was released in 2004... If you never played it, go give WoW a spin, if you've spent the last few years in it like alot of us, just forget about it... it's spent like a worn out car from the 80's. After playing three days of TR, I went back and logged my epic shaman on WoW to participate in a guild raid... the game has lots of charms, but let me tell you... after a couple of days on TR it felt like WoW was in slow-motion. I couldn't believe how boring and slow the action was by comparsion. On the downside - TR needs TONS MORE CONTENT. I've been having great fun at the beginning, but there is only one playable race and a relatively shallow character progression tree. These are not deal breakers (especially since it supports the games mythology), but they need to compensate that with an insane amount of broad in-game content as you get to higher levels. Some alien factions with new gear sets (for instance) would be sweet (might as well steal what WoW got right). And this talk about not having epic end-game instances? That's just silly - put them in IMMEDIATELY. Some people will play them, some won't, but everyone will want to, casual gamer or hardcore... by the way that wasn't a WoW idea, it was invented by the original EQ with the Planes. It didn't matter if only 1 in 50 people ever saw the Plane of Fear on the original lvl 50 game, everyone talked about it and wished they could go. When you saw that one person on your server with Cazic Thuuls Robe, you looked at that person with awe and wonder and wished that it was you that had gone a fought the gods.
