The fact that these clearly talk about building on an older system (not sure if they mean PSU or not) does worry me slightly, they need to ditch every last thing from PSU and either focus on enhancing purely what made PSO great, or start from scratch.
Also, LOL at 'Infinite content', I assume that's related to use generated levels (Which had better be more than lining up rooms in a specific way) because there's no way in HELL ST will provide enough content that isnt recycled to last more than a year, even then it'll probably be on the disc on release already. <- If they pull that same shit again like with PSU, there's on way i'm even buying the game.
Come on ST, redeem yourself even just a bit =/ Oh and by the way, I'd take ST's promises with a pinch of salt, I seem to remember them wanting PSU to continue on for 6 to 7 years or something? It's like 4 years old now and hasn't recieved anything more than a couple of number changes since that last craptastic expansion they did.
EDIT: I thought I'd comment on the hilarity of 'improved AI' and 'EVEN MORE ways to raise your character. PSU had some of the blandest AI (They could walk forwards, amazing) and crappiest character development systems about, they'd seriously better come up with something good for this if they want to compete. They've got some huge contenders in any field thye might choose to enter, Diablo 3 for the 'dungeon crawler' type, Guild wars 2 for the semi-instanced-free-to-play type (Seriously, I think they should totally steal guild wars 1's system, think it would suit them to a tea, though perhaps allow more people into the outdoor zones than just your party) and WoW/FFXIV(lol?)/star wars in the mmo field.
