Really wish they'd re-release games 2 & 3. Seems weird to go from #1 (which was awesome by the way) straight to #4.
Yeah, they really should have brought 2 and 3 to modern systems by now. I mean, since the original is on everything including PC, then why not do the same for the sequels?
You can get 2 on the VITA store already, 3 is still MIA though.
I remember reading somewhere that 4 and 1 have a lot more to do with one another while 2 and 3 are more like side stories that tie into the canon, but have less of a connection.
In any case, if 4 does well enough I could see 2 and 3 coming next year in a collection similar to the God of War PSP games.
