I've not heard of Umlimited SaGa. Unlimited SaGa however has a nice sound track, but looking at it's contents (loads of battle themes and some other theme) plus loads of remixes of them, it does appear that there is little to do in that game or that it's boring. Only SaGa game I've played so far is Romancing SaGa 3 on the SNES, and I couldn't finish it because it got so boring, even though the battle system was pretty nice and more interesting than many other RPGs
