It's important for new game designers (and gamers to an extent), to play and learn about these retro games that almost seem like they have been forgotten. People nowadays will seldom try to set-up a whole emulator system just to play one game, and to a point it's why these systems are used by individuals who have already played old games and want to scratch that itch again (wink).
You don't play this game just for the nostalgia side to it (although many people will). I grew up playing Playstation 2 games, and now have a PC setup. Playing this game made me feel like a child!
It has interesting enemy design, each one more different from the other, based on some simple core concepts that lead to a whole lot of tactics and tricks in order to beat said enemies. Undoubtedly, it might be one of the more interesting games I've played this year; just for it's depth in gameplay alone!
I think this is an ideal way for younger audiences to experience old games. The graphics are the same, as is the music and everything else; But the gained accessibility of having it just there on the desktop is like no other!
