For sure RTW should get Strategy game of the year. I'd probably say it should get Game of the Year if it wasn't for the bugs and problems that it has still. One thing is for sure - all the FPS that came out this year are going to be hard pressed to not just become "one of the big 2004 FPS releases".

Also, sequels to groundbreaking games can still be great - but they're unlikely to be as groundbreaking as their predecessors; so they're scrutinized more by the 'vets'. Like me with RTW right now - it's all about expectations and previous experiences with similar games.
