I finally finished downloading and installing the Early Access yesterday, at 16h00, so a good 8 hours before the official launch! That was well worth 2 days of non-stop downloading.
So I played a bit last night, and had a blast! The only downside is you need a really good machine. The game was as laggy as the first time I went to Ironforge with my crappy old PC. One minute you're entering the gate, the next you're in the trench ice-skating against a wall. I'm buying some more RAM and a new graphics card, which should help quite a bit.
The good side is that even with my crappy card and low RAM, I had a lot of fun. The customizing of characters is really good, very detailed, very precise, and you can get some very distinct looks. Especially for female characters. Tare, my lvl 5 demonologist is devilishly hot Any resemblance to any other real or fictious character is purely coincidental, ofc. It's not like WOW where all NE females basically looked exactly the same.
After 1h30 of playing around with the different shapes and tatoos of scantily-clad women, I finally went in-game. You're basically taken by the hand and led through the first few levels, it doesn't feel as free as WOW, there's not much discovering to be done, at least at first. But I heard it was just for those first levels, like a long introduction into the mechanics of the game.
The combat system is really pretty cool, more involved, the gore is actually quite fun, and you can do some pretty cool moves, even at lvl 6, which make you go "ooooh, nifty!". If you speak like this, of course, which I don't, I'm much more manly, I say "Fockin 'ell bruv, that's rock hard!!" or something. So yeah, anyway, the combat is a lot of fun, and the whole thing of not being able to go through someone's body is very refreshing, and seems to work ok.
Having only played enough to take 4 classes to level 6, I can't say much about how the game develops later on, nor the PvP, nor the imbalances that people are already whining about in gen chat. But if you can get past that, and you have a really good computer, it seems like it could be a lot of fun.
