in bold: Well, you may be right. Check first to make sure. In my experience, do research first to know about what you're getting yourself. This helps prevent problems in the long run.
Hmm, considering that M2, H3, and GTA IV all have a broader experience online, you may be a tad out of luck. Granted, I haven't really played any of those games, that's just what I've heard about them from IGN. Though, I'd say they may have a decent single player campaign, so it really wouldn't matter that much.
Very true. I find that I've been torn between the 360 and PS3 numerous times; I've seen multiple X360 games that I've considered getting, but I've also had my eye on multiple PS3 games. The bottom line though, is my current monetary status; you can't really go too far if you can't pay for it.
Back to the topic though, do some research, know what you want and see if it matches what you need, and go from there. Works on most accounts.
