Final Fantasy Legend 3 (Game Boy).
I have played this game many times over the years, but this is my first time playing the game since playing its DS remake (which completely changed the game mechanics to the point where it's arguably a completely different game).
I am not using the gold underflow glitch this playthrough, but I may experiment later with the barrier skip later in the game. (Yes, this game has a barrier skip glitch.)
I spent time leveling up to level 11 before Lara so that I could turn Arthur into an IronLady. It's nice to see Robots being useful again, especially since they weren't that useful in the DS version. (Note that the opposite holds true for Monsters.) It is a bit odd having a game that uses experience levels is balanced fairly precisely (killing enemies with 2 hits is the norm), but then having a character race with a growth system that lacks diminishing returns to break much of the game. (The game *does* eventually catch up, but not for a while.)
By the way, the original Game Boy version has levels and experience points (as I mentioned before), but the DS remake does *not*, instead opting for a system that's more like the other SaGa games, but with the added factor that stats can increase mid-battle.
