I leveled a party to 99 - twice now - and from about level 60 on, humans and mutants are overwhelmingly stronger than the other creatures. For casual play, the hybrids and robots will certainly get you through the game - Saga 3 is very easy, and magic potions/tents/healing springs make every dungeon very easy to simply spam your strongest attacks. (It's also very easy to grind your way past the difficulty curve in a couple of hours in the right spots). If you're min/maxing and doing the completionist thing, Mutants spamming Flare/White/Nuke for mobs and humans swinging Excalibur and Masamune for bosses are the pinnacle of devastation - as stats go north of 99 on their primary attributes pretty quickly at higher levels. Saga 3, (Mystic Quest Alpha in reality), was a product of it's team and time. As someone who bought it new when he was in High School, it was amazing to see a nearly &quot;fully featured&quot; final fantasy game on a hand-held. You had auto attacks, the game remembered what you did in previous battles, a reasonably full spell list, lots of NPC's, good music for the format, a flying headquarters, lots of inventory space and cool consumables (again - for the era). At the time I LOVED that your weapons didn't shatter after 40 or so uses, though, over time, I've come to appreciate the Saga mechanics. Also, compared to what was available, the translation was at least understandable. (They had to conserve every word due to the ridiculously small cart size). To modern eyes, the game looks pretty forgettable, but in it's era, Saga 3 was one of the most involved handheld RPG's on the market, in terms of mechanics, story, music and depth.
