I recently purchased the Sega Genesis version of Sonic The Hedgehog. Funny thing is that I purchased a much older version that was made for the Sega Master System (which came out before the Sega Genesis). The graphics looked more dated and the music looked a bit off. These however were the early years.
I'm very retro these days because I'm kinda like most people watching television now. I don't wanna get so involved in a game that I forget I have a real life. You can put away games like Sonic for a month and come back and still feel like you are having fun. Games like Resident Evil 4 require more attention to details and are a bit taxing for me.
Playing Sonic The Hedgehog, or games of that bygone era, isn't a step back to me. The times were simpler, but the older games are just as hard, if not harder than the newer games. I feel in the case of Sonic that in order to fully max out the interest, you have to choose how you view each world you visit.
Aside from beating Dr. Robotnik, you have to obtain a bunch of coins which are essentially how you stay alive. Searching for these coins all throughout the worlds can give you interesting ways of finding shortcuts and having fun at the same time.
Sure that's just as taxing as RE4, but your brain doesn't feel it quite as much.
Anyhow, I'm done blabbing here. More Sonic posts are to come soon on this blog. Perhaps someone can give tips.
