I'm torn about Space Siege at the minute. It could be awesome... but it could also fall flat on it's face. :(
It's'97 again! Rush and shoot, and if U die, rush and shoot again, nothing bad happens. There are no forks in story line, no decisions of any kind, no selecting technician/fighter sidekcick, nothing... Missions are - go to sector X, visit locations A, B and C for main quest, and by the way you WILL pass trough Y which is sidequest... then back to base, and over again... If you find locked door, that is because they are planed as shortcut on your way back... and can be opened from other side... Only "thing" is decision about cybernetic parts - eye, hand, arm, legs, ... more you install, more powerfull you are, but less human...
That is not enough, not after Mass Effect. There is no feeling of that heavy and thight situation where lives depend on you. All coridors are the same, and if you need to protect someone opening the door, you can die and come again from last save-room, he will be there waiting, and aliens will not attack him at all...
So... Diablo was "intellectual puzzle" when compared to this game. Shame on yoo Chris Taylor! Shame!
