I've heard good things about Wild Arms. I got a Playstation Classic at a pawn shop recenty and Wild Arms 3 was on there.
wa1 is interesting but I couldn't figure out how to advance forward with the story on the girls route. I assume since they allow you to switch between the 3 protagonists that I needed to go further in the other 2 characters or something.
2 is more straight forward and minus navigating due to some sections of the world map being linear one way paths. The bomb collar guys specifically. I liked it the most out of the 3 since it had more characters than the others and I didn't find one I disliked. Also unlike 3 it doesn't use the shitty line group system that dq8, okage and other games do where you can't target all enemies for a target all spell or skill.
3 is super long, has really clunky 3d platforming like most older games. But for the most part it and the bad camera angles were negligible. Minus the rising and sinking platforms one. That was terrible and nearly made me quit the game. The biggest issue for me with 3 is how you have to waste turns to charge your gauge so you can attack early on. Since the starting amount is based on characters levels iirc. Its animation speed and turn length are also on the longer side than I would like. Virginia is overly preachy and it gets annoying listening to her constantly on her soap box the near entire game. She's similar to Illana Laluna from symbionic titan in that regard. Or Snow Villars going on about being a hero from ff13.
Character balance was also pretty poor in 3. since Virginias main uses are healing or using target all (doesn't always work since enemies are in groups so outside summons you can't always target all) items skill specific to her and her high speed. Gallows is your main mage since he's the only one with a target all version for magic. Like virginia it doesn't always work. Gallows is super slow though so that hurts him significantly. Clive is your main attacker since he has very high attack power. But he's super slow as well. Jet is the odd one out since he has high speed close to virginias and all his stats are otherwise balanced making him a jack of trades master of none.
3 suffers from the target all issue games like dq8 and okage have. Only a select few things actually have target all like summons in wild arms 3, overdrive buff thing from ari in okage, I think a boomerang attack in dq8. So it makes battles more tedious just because of that and how limited you are in doing so.
