Random battles really don't bother me at all. I don't really mind what kind of battle system it is as long as it's not a crappy one (FFXII). The most fun one I played recently was Rogue Galaxy. But yeah I still like turn based systems too, I just wish they'd give us more to do. Basic TB systems like "attack, magic, skill (Usually poncy shiet like Steal etc) and that's about it. That crap is boring. Needs more limit breaks and single, double and triple techs like in CT. Give me those and I'll be happy has can be.
Also, I agree that world maps need to come back. This linear progression through games is so failridden. I don't mind a game having a linear plot but exploring a world map and finding hidden places or new side quests is just awesome.
I do find it kinda funny how many people complain about difficulty of RPG's. The game doesn't force you to keep upgrading weapons or magic or any of that shiet. If you want a challenge so much then just stick with the basic equipment or something. It's not really hard.
