I get what you're saying, but it is well worth it. Most games are what... 50-60 dollars these days? Give me 5 mega man games (or 4 mega man games with downloadable upgrades) and that's well worth it to me because of the fact that it *is* nostalgic. I literally can't tell you how much adrenaline was coursing through my body when I was down to the last quarter of my life and Magma Man was nearing his demise, I had no E tanks and no more lives. When you kick that fucker's ass and he explodes, that feeling is just like being a kid again. I had this stupid fucking grin on my face for the first hour or so of gameplay. I couldn't even contain myself... it was too much fun!
Maybe it's because a lot of shit in my life sucks right now that to feel like being a kid again before i had any worries or responsibilities is well worth that money, but the game itself fucking owns. Also, Proto Man is supposed to be able to slide and use charge shots (i believe?) which would make the game a completely different experience.
Sorry for being a dick by the way. Cheers.
