I'm a beta tester in the 2 big MMO imminent releases - EVE and Planetside. Neither are ready for release which I think is a real shame because they both have huge potential. Of the 2, Planetside is certainly the more stable but it's got a way to go yet. At very least, they've got to fix the memory leak, at least what I assume is a leak as it takes up my 768MB, a decent figure.
The biggest gameplay problem is probably the lack of a real goal. Taking bases and then islands (or continents, as they fancifully call them) is fine, but a few hours later it's gone back. The game is supposed to last, say, a year, yet the biggest target in the game takes a few hours usually, a day or so at most (and any one player won't be involved in most of that unless they're in an Asian internet cafe). Sooner or later this will get repetitive...
That said, the game is very enjoyable and I've had a good time. I'd consider subscribing for a while, although I might wait a couple of months for the problems to get sorted out.
Cheers,
