Ok so I just finished Peggle on Sunday, and since then I've been wanting to play more Popcap games. I felt like playing some Plants VS Zombies, I have it on the PS3, Mac disc, Steam and iPhone. I was going to play it on the Mac, but I was like fuck discs man, and I spent £6.99 on the Mac App store and bought it there. I even know full well I had it on Steam, so I really do not know why I bought it on Mac, but yeah I did.

Do you own multiple versions of the same game, if so what game and how many?

This game is probably the worst for me for multiple versions:

Steam

DS

iPod

Blackberry Playbook

I totally considered getting it for PS3 but... no. No. No. I can't. I can't.

Admittedly, I don't really play the iPod version that much. I beat the Steam version. I'm playing through on Playbook right now because it just looks so pretty. And, y'know, what else am I gonna do with a Playbook, right?

The one version that still truly has legs for me is the DS version, since it has the unreasonably fun VS mode. My fiancee and I will bust that occasionally and have a pretty solid time with it.

I own Twilight Princess and RE4 in both Wii and GC and that's about it.

I own 4 copies of Catherine (Japanese 360 & PS3, English 360 & PS3), 3 copies of FF13 (Japanese PS3, Chinese PS3, English PS3) and 5 copies of Devil May Cry 4. And this is just off the top of my head.

PvZ and the first two Oddworlds are my most numerous. PvZ and PvZ GOTY on the PC, and PvZ on the Kindle Fire. Oddworld on Steam, GOG, and D2D.

I think I've bought World of Goo close to 10 times now.

Darn, I thought you were gifting Plants vs. Zombies. I don't own a copy.
 
As for your question, I did in the past, but all those games got traded in. I did own Tiger Woods PGA Tour 2005 for 4 different platforms.

I have peggle on ipod, iphone, 360, steam and DS. I have a peggle problem.

About 10 copies of Starcraft but I have no idea where ANY of them are.
