Tabula Rasa is Awesome
Now, it's a beta, yes, buggy, yes, lacking content, definately, but it's still awesome.
I think the third-person shooter MMO is a good sample of how the control interface of such upcoming joys as Hellgate: London might work, and I can say I'm really looking forward to it.
The crafting system has promise (needs work at the mo), and being in Australia, the lag is dreadful (not that noticable though. Great compensation. Never once rubberbanded with 900-2000ms ping).
The weapons are delightful and colourful, and the armour ranges from Unreal Tournament chunky-style to casual clothing, to spacesuits... and so far I've found that many recipes for armour dyes, it's almost silly.
The customization is wonderful in that respect.
Missions, well done enough, and the bonus XP system (rapid kills get 2x XP multiplier, up to 6x if you slay a lot of stuff really quickly) absolutely kicks butt.
The classes... I feel they need a bit more diversification, and if the customization and specialization stops when it does in the Beta... well, that'll suck, and suck hard. You get to specialise once at level 5, again at 10, and then once after that... no new spells, new skills, or nothing other than these three or so upgrades? I hope not.
Overall, it looks, plays and feels like a beta, but it's a damnsight more enjoyable than plugging away at WoW, hopelessly underdogged by the no-lifers, or missiongrinding EVE.
