Whenever someone mentions mmo I think mmorpg, which immediatatly springs to mind Automated Combat. Sure, people brag about how great it is with all it's micro-management, but at the end of the day, it's crap. I'd like to see Elements of shooters included, mabye some close-combat action from games like Ninja Gaiden or something like that, or at least something like Oblivion. Whether my prayers will be answered or not, time will tell.
Next thing, subscriptions. I personally think it's daylight robbery, we have to buy the game and THEN pay to actually play it, and then they expect you to buy expansions as well. Hopefully THQ are gonna be somewhat smart and have a one-time purchase thing, something like the Battlefield series or something. Time will tell
