Though casual games take a lot of abuse here in the forums, and in the gaming press & online community, we all play some of them. What are your favorite casual games (and for which console, handheld, or pc)? Are there casual games you don't play that you think are well done (a good example of this for me would be Order Up)?

My favorite casual games:

Tetris (Multi, I have NES(Tengen), GB, DS, Wiiware)

Pinballs Greatest Hits : The Williams Collection (Wii)(Psp version is ok too, but the Wii Controls make it)

Luxor (Multi)

Peggle (PC)

Wii Sports (Wii)

Buzz (Assorted Titles, PS Family)

Dr Mario (NES/VC/GBA)

Guitar Hero/Rock Band (Multi)

Ultimate Brain Games (GBA)

Bejeweled (Multi)

Zack & Wiki (Wii) (added)

Lumines (PS Family)(Added)

I think the following are well done casual games:

Nintendogs (DS)

Scene It (360)

Singstar (PS Family)

Karaoke Revolution (Multi)

DDR (Multi)

Diner Dash (PC/DS) 

That's just off the top of my head, there are a ton of well made casual titles. Discuss.....

Geometry Wars (almost bought an original Xbox for 70 bucks just to play it)

Tetris

Wii Sports
Singstar
Buzz
Tetris
Lumines
Diner Dash

Geometry Wars is a phenominal game, but would it be casual? I always considered almost all SCHMUPS "Core" titles.

I forgot Zack & Wiki from the original post...

Zack and Wiki is a core title.

Some online flash games, Wii Sports, Wii Play...

I can go either way on that. REALLY casual players I've let play it seem to enjoy it (but probably not enought to buy it)

rockband and anything nintendo

Peggle
Picross DS
Tetris

Tetris, huh?

OK, so somebody can play that game 8hrs a day for months and its casual?

Believe, u got balls for startin this thread but its stupid and Z@W aint casual dude

GH is debatable, i think core but u know f--k these damn labels are bullshit
