Except for Shining in the Darkness(which isn't one of the TRPGs and an absolute garbage game,) I've never played anything other than the first Shining Force and haven't been interested in playing another game in the series because of it. I've played many TRPGs and even though it's not close to being the wosrst of the bunch, it's definitely not close to being the best of them. It does have the basics set up nicely, but there are a lot of issues with the game. I wouldn't say it's great. Hell, I'd be lying if I said that I thought it was good.
Shining Force is garbage.
