What games alone are worth the purchase of a console?

have you ever bought a console because of one or more games that you couldn't find elsewhere?

I think it's worth buying:

Wii: for Super Mario Galaxy series, New Super Mario Bros Wii, Metroid series, Zelda series, Wario, Super Paper Mario. Mario Kart

ps3: Uncharted series, Gran Turismo 5, Metal Gear Solid 4, Heavy Rain, Little Big Planet

360: Halo series, Alan Wake, Forza 3, Fable series, Gears of War 2, Rare games

Multiplats aside ( the 360 wins there imo ), exclusive-wise my preferences go:

1. Wii

2. Ps3

3. 360

wii-super mario galaxy (although this is not the best platformer this gen) for xbox 360 its h3 and i guess for ps3 either god of war 3or mgs 4(chose two cuz i haven't played either games)Microsoft1234

I'd say Gears 2 and MGS4 justified the purchase of my 360 and ps3... and as for the rig, S.T.A.L.K.E.R, supreme commander and crysis are definitely mentionables in my book

None. Although i did buy a Wii just for Zelda TP. which i would advise against doing.

1. Nintendo 64: You could buy either Super Smash Bros, Goldeneye, or Perfect Dark, and the amount of play you can get out of any of those games warrants the purchase of the system. In fact, the reason I don't have my N64 is because I borrowed to my cousin when he went away to college--where he only had SSB the entire time there.

2. Gameboy: I remember when the original gameboy at demo koisks all that time ago. It would be worth it for Tetris, alone.

--I suppose you could put the gamecube/wii in there for Smash Bros as well.

GoW3 was the deciding factor between 360 and PS3.

For me Metal Gear Solid 4 and Mass Effect alone warranted a purchase of each system. I thought Smash Bros Brawl warranted a purchase of a Wii, but it just didn't have the... quality of Melee.

Halo for 360, and SSBB for Wii

I say this because you can put hundreds of hours into each of these exclusives pretty easily because they're so much fun.

For one game no. mrmusicman247

I agree, no one game is worth the purchase of a console.

Lets see:

Wii: SSBB was the reason I purchased one, Monster Hunter Tri is the reason I haven't sold it yet.

360: Gears series was the sole reason I bought a 360. Halo 3 and Dead Rising were just bonuses.

PS3: MGS4 was the reason I bought a PS3 before a 360.

A lot of people are saying that one game alone isn't worth a purchase of one system. Well, for some it may be. If one game can continually provide hours, days, years of entertainment for that person, why not buy the system for that one game?
