I bought PS3 for Grand Theft Auto IV, but it also came bundled with Uncharted 2: among thieves. What a great new franchise i though it was when i first played it, it had me hooked for the other games in the series, thats for sure.
I'm glad i bought it as i got to play all of rockstar's awesome games plus uncharted 3 came out since then as well. Purchasing a PS3 was so worth it for everything, it got me through an amazing generation of games and now even more in 2013, i know i will love last of us, GTA V and Beyond along others.
While i don't know if it counts, but i also bought a decent PC to play the mods that came out for call of duty world at war and minecraft, and now realise PC really is the format to play games on. Games are far cheaper because of steam and tend to play better on mouse and keyboard. Also, RAGE and sleeping dogs looks amazing on maximum settings on PC.
PSP- got it as a birthday present 5 years ago and it came with the Simpsons Game (i'm a big Simpsons fan)
I'm glad i have it as i discovered many franchises on it, including GTA, Gran Turismo, Syphon Filter and others. (at the time, i only just got into gaming again, since i found my mum's old SNES and wanted to play it)
I want 3DS for it's Mario and Zelda games, might try Pokemon too.
I want Vita for Uncharted, Gravity rush and Assassin's Creed.
I want Wii U eventually for ZombiU and Lego City.
Xbox One, PS4 and Switch (+ Many Retro Consoles)
