Super Mario Galaxy
imo no developer can match ead at their best.
i love intsys and old r&d1, they're responsible for many incredible games, but even they can't match ead on form. all my favourite development teams are within nintendo and personally, i'm happier with the games of these teams than i've been for years, using the structure shikamaru ninja has talked about.
ead has been refined to perfection! so many incredible teams creating so many amazing games
spd1's warioware games are brilliant (although touched is the weakest entry and could've been better if it wasn't rushed). twisted and rhythm tengoku are genius! stunning games which i still play now, even though i've completed them and smooth moves looks like it could be the best game in the series!
intelligent systems is stellar! fire emblem, advance wars and paper mario are consistently amazing and super paper mario looks awesome! they also help the warioware games with no doubt valuable contributions.
game freak is another amazing team. retro will hopefully fix the short comings of prime 2 and release another stunning game in corruption which lives up to the excellent original prime. task force development has created brilliant games in band bros. and brain training. hal is also a great team and i'm looking forward to playing pokémon ranger.
also, i think it's a mistake to assume every producer/director wants a huge team.
