I know alot of games have used similar graphic engines and environments in the past.. probably to save on money and time, ect. but have you ever played a game before that has had the music remind you of another games score, maybe even having the same sound effects?
Now, i've been playing Y's 1 and 2 for a couple of days now, and have noticed that every time you open a treasure box or find something that the music is almost note to note the same as the discovery music in Metroid. Not only that, but in megaman 2 i've noticed that the intro to Flash Mans stage sounds alot like the music from the pit (undergound) section of Clash at Demonhead.
I'm probably just thinking too much into it. I mean, how many different sounding games can be produce? However, I would still like too know if anyone else has run across similarities in game music.
