Disaster really turned me off. It looked too... "Sony"? And I just, I really don't like those kinds of games. However, Nintendo is involved and the Wii remote is being used so if it's possible to make a game like that interesting to me, Nintendo might actually find it.
Hammer actually has my interest. I love how, by todays standards that is, retarded it is. How many games have you played where the entire game was ruined because the developer just kept adding stuff and adding stuff, not because they thought it would make the game any better but just because they thought it was "cool" or it would sell better? Simple games rule! Of course Nintendo will probably make it only seem like it's simple. Underneith it will probably be incredibly complex and evolved, we just won't realize it because of all the fun we're having!
My only qualm is that it's being developed by NST. I haven't really liked anything that they've done so far, and I was rather dissapointed with their treatment of WaveRace on the GC.
