For those of you telling me that I need to play the others:
1. How long are those games in hrs approximately?
2. Should I take back MGS4 for now? I haven't opened it, but my mom got off of an online store (I think for $20 off), so I'd have to mail it back in... and I can't trade it in to GS, because I know I'd get ripped off for it...
3. Should I just keep it?
What should I do?
