It is hard to think of games that would benefit from a Tactics style redux, but a Dragon Warrior game like this would be cool. I liked the Dragon Warrion Monster games. You could start the game out fighting a group of low level Slimes and somehow recruit the lot of them onto your team. In this way and in the tradition of DWM games you could also trade monsters out for stronger monsters anytime. It'd be a neat twist I think.

I'm starting to see how something like this would only really effectively apply to games that already have RPG elements, though a LoZ game would also be neat. Again your character could be assisted by Monsters or Wildlife..... after all, Link has always had a strong connection to Nature. Though having a team consisting of Link, a Deku Scrub, a Goron, a Zora, a Sheikah and a Hylian would be pretty cool too . They fill all of the appropriate rolls.
