FC wasn't that buggy for me at launch... this one has crashes when I play in fullscreen mode and I alt-tab...however turn off fullscreen mode and issues go away...and it's got some weird magical best non-fullscreen mode that looks exactly like fullscreen mode.. I can't tell the difference at all, not even a flickering tab on the top when I alt-tab or something, just play not fullscreen, it's the same thing only no crashing when you alt-tab.
edit: Played a few hours myself now, didn't say what I thought because I didn't know how to express it accurately.
It's what I expected, which is great... Obviously the first time you play thru an RPG is the best time, but FC was unique where replays had more meaning, and when you re-play it, while it isn't as wonderful as the first time in many ways, it's also better in others, like you can fully appreciate it the 2nd time plus, though is now predictable.
SC is now like... the wonder of a first time thru, with the appreciation of someone who played thru FC already, the best of both really. It's not that I think it's 'better' than FC so far, but I am enjoying it more so far for reasons that aren't just personal taste. Hopefully that made sense.
