Game Days Rerevisited: I bought X for Y, but ended up with Z

I asked this question in Random some time ago, but was thinking about it again as I powered up my Vita for the first time.  In Random, I asked what games caused you to buy/ask for what systems.  Instead of just regurgitating that same discussion here, I thought I would add another step.  I often found myself buying a system for a certain game, but ended up discovering a whole new series down the road.



I bought an Atari 2600 because it was 10 dollars in a thrift shop and came with 20 games, but ended up discovering River Raid.
I bought a NES to play Zelda, but ened up loving Super Mario Brothers 2.
I bought a SNES to play Final Fantasy 3 (6) and Chrono Trigger, but ended up really enjoying Dr. Mario.

I bought a PS2 to play Final Fantasy 9, but ended up really enjoying the Tony Hawk series.  The PS2 was the Golden Age of gaming for me.  I discovered so many series and still buy games for it.

I bought an artic DS to play Final Fantasy 3 (the actual 3), but ended up discovering My Chinese Language Coach.
I bought a PSP to play GTA Vice City Stories
, but ended up using it as a music and video player.

I bought a PS3 because my wife wanted a Blu-Ray player. Weird now that I think about it. There was no game I was excited to play on it.


I bought a 3DSXL to play SMT IV/Bravely Default, but ended up really enjoying the Theathrythm games.

So after you bought a system for a game, what other games did you end up discovering?
