I remember hating this game as a kid cause the bosses were frigging hard to beat. I spent hours on boss 2 and grinding was fairly slow so you couldn't exactly power level yourself out of a bind.
12 years later, i find myself wanting this game again because customizing gundams is cool and honestly I really appreciate alot of the small things they put into the game. Towns had subtle hidden paths that rewarded you and talking to npcs helped you find them. The bosses that were 'hard' to me were actually quite easy because the skills available to you gave you enough strategic depth to win. Best part of the whole game? Minor feature but the party switching mechanic didn't automatically end your turn so I played with everyone including the guest NPCs that'd join your party.
There are some issues like unnecessary walking for some segments of the game. Really high chance of stun locking you at the first milestone of the game (where i'm at right now) which led to fights being drawn out and tedious because you were given 2 guest NPCs who helped you circumvent the issue slowly.
Overall, this game has a lot of good going for it, glad I gave it a second chance and if you're starving for a real classic JRPG with GUNDAMS, Ms Saga has you covered.
On a side note, If this game was re-released on steam, I'd love to purchase it again just to show my support.
