I'll definitely be getting the Tales of game (As well as the new Tales of Symphonia sequel for the Wii), but I'm a bit iffy on IU. I really want it to be good, but Tri-Ace hasn't performed well in my opinion. I've only played the original Valkyrie Profile on PS1 and Star Ocean: Till the End of Time and didn't like either. I remember hearing so much hype about Valkyrie Profile for years before I finally found a copy on eBay and purchasing it. I enjoyed the battle system well enough at first, but by about halfway through the game that was the only thing I even remotely liked about the game. It quickly became tedious and boring and I ended up selling my copy shortly after completing it (I never sell games but VP was selling for quite a bit at the time and I didn't like it so I made a $50+ profit). I couldn't even attempt to complete SO. The battle system was fine, but I hate to say the voice overs actually killed the entirety of the game for me. They got so horrendous early on that I had to quit playing the game and there wasn't enough left to the game that I liked to make me keep going.
So I'm a definite yes on Tales of (unless reviews shed some light on some reason I would hate it) and pessimistic but hopeful for IU. As long as there's enough meat to the game that I can appreciate I'll probably get it, but I'll have to think carefully about it and read tons of reviews (and I mean read them... I don't care about scores). It's already apparent the voice acting is largely mediocre and the English lip-syncing is essentially nonexistent, but if the story or game play are great (or both are moderately good) I'll end up grabbing it.
