@gRaViJa That's not really what's meant, in this case, by unencrypted game. In this case, it's a game that has all of the original files included so that a user can open it in RM and poke around and see how things work. What you have linked is a completed, deployed MV game.
"Omega Arena" doesn't have any .rpgproject file to open, but if you do place one from a tiny demo in the www folder you can. However, as an RPG it's just a long grind of escalating battles with a lot of Yanfly plugins to pretty it up. There's even region plugins turned on when there's no regions defined in them, and none defined on the one map.
I'd really like to see some MV games to learn from, but these weren't them.
Awesome idea! Are there no unencrypted games for MV though? I don't own any other rpg makers. Sorry if it's been asked didn't have time yet to read the whole thread.
*edit* so nvm I just noticed this thread is very old lol. The op is probably long gone by now. But I'd like to find some good MV games to learn from. Based on replies the MV games listed so far are no good for that.
@MaGicBush : I don't know of any either. Though, if you don't mind, can you PM me a list of the kind of events you'd like to see in an MV game? I'm curious what others are looking for in that, but since it is off topic it's probably best if done via PM.
