With Company of Heroes 2 just announced, there just might be hope for a Space Marine 2. Games Workshop IP seems to sell well for THQ, and with the cancellation of the MMO, I expect that the work already done on Dark Millenium will not be wasted. Ripten had an excellent article
here about the changes coming down the pipe.
As lag goes, I don't seem to have too many problems. It's possibly a function of the absolute lack of confidence I have about my skills (especially after the drubbing I got in my Spiral Test, I changed classes because of it), but could also be due to the internet in my area, which it quite quick. Either way, I try not to let it bother me, as I have little to no control over it. I do have my rage-y moments though.
