I browsed around for about a good half hour before deciding where to make my first post on these forums, and I can say, without any doubt, that I won't find a better statement anywhere else even if I read every other topic on here. SaGa Frontier was amazing, but I despised SaGa Frontier 2, refusing to play even halfway through that game (though, I don't even know where 'halfway' is. I put in about 5 hours or so on about 2 or 3 new game files and just never got into it.) I recently went back to the old original Gameboy ROMs for Final Fantasy Legend II, the closest I could find to a good game that has a very similar system to SaGa, but after beating that it's gotten me missing the series once more.
I'd have to come back to this when it's not 5 in the morning. Threads of Fate could've used a sequel, though I'm sure there's many, many other games that are slipping my mind at the moment.
Edit: Damn, you guys have good taste. Reading through just the first page I see Threads already listed along with Vagrant Story. Great calls. I might have to do more digging.
