favorite summer time games?

While the temptation to go outside and do stuff while the weather is nice can be overwhelming I'm sure we all still play our share of games during the hot months.  What's everyone's favorite games to play during the summer, past or present?

1.  Madden (always a nice warm up to football season)

2.  Zelda: A Link To The Past (I spent an entire week one summer playing this, I always bust it out when summer starts)

3.  Rhythm Heaven (a more recent one, it's been glued into my DS for the last month.  The music makes for nice bus rides in to work)

I guess the games I'm playing right now, which would be:

Dead Rising (OK, haven't actually played it)
RE5 (I have yet to reach the part where the game gets racist)
Fallout 3 (I'll save my opinions for my blogs)

And many more...

I just bought Shin Megami Tensei Devil Survivor for the DS. Its no Persona 4, but so far its pretty good.

I love playing Halo matchmaking during the summer, it is so addicting.

Every season is Monster Hunting season

i beat fable 2 again with all the dlcs with a good character (last time i was the asshole) and ill probably spend a lot of time playing battlefield 1943 as soon as they fix up the servers (until arkham asylum comes out in august anyways).

Finished Fallout 3 the other week, and i think it works pretty well as a summer game, what with the hot, desolate, desert-like wastes.
