I only bought the vita version this time for oddworld. I didn't realize there is only a little over 150 region 1 games(untll about 2 weeks ago), and I already have 40+, so it looks like im collecting for that system now. The reason I didn't buy the ps4 version, was because I don't see myself going for a full set of ps4 games, and its not super unique. Have it on psn, and its same trophy list as the ps3/vita. Its also not a RPG, which i go out of my way to collect for. Had it meet any of those other criteria, I would have picked up the ps4 version. The DLC on the disc, wasn't a factor for me.
