Mega Man soccer for the win! I don't own a copy of it, unfortunately (and I've yet to find very good emulators for the Mac... to be fair I haven't looked very hard). What I remember is that it was addictive and piss-hard.
My original plan was to review 1-6 and then maybe do 7 and 8 (since they conclude the Mega Man Collection) and possibly move on to 9 and 10. I was even tempted to pick up the Mega Man X Collection again (I sold my last copy) and do a run through and review of those... I think it goes up to X5.
Now, I'm not so sure. I'm almost more enamored with the idea of just doing 9 and 10, since they are in the "classic" style. Mega Man 7 is a game I've played a lot (and I did just play it again) and I enjoy it a lot, too. But it really feels like a completely different game and I'm not sure what angle I would take. A lot of the things I tended to talk about, like immersion in the Robot themes, almost seem redundant with the high powered graphics of the SNES. And the design sensibility is totally different. Everything is bigger, Mega Man controls with a very different feel, and there seems to be a lot of emphasis on difficult close-call jumps and enemy gauntlets. And Mega Man 8 is totally different from even Mega Man 7, from what I remember about it.
Regardless, I think the real reason I've suddenly turned against the idea of doing more reviews is that, during playing 6, I realized how much of an end it really was (see the review and also Dagoss' spot-on comments). When 7 came out, Mega Man X2 wasn't far behind, and then neither was battle network, and legends, and all the other stuff that now defines that very expanded universe (and heck, I didn't even touch on all the gameboy games that were coming out each year). Mega Man really did transition after six into something a little, if not a lot, different. It feels like a natural stopping point.
Still, I haven't decided yet.
