Rogue Galaxy: Good: Combat, Colorful World and Story. Cons: A bit annoying in diffculty.

ToA: Good: Kick ass combat, good story and visuals, Cons: Cliche in tons of parts.

Xenosaga III: Good: Combat, Story Cons: A bit overwhelming, not for people who hate deep stuff.

ZoE2: Good: Interesting visuals, grand action, good story. Cons: Bad voice acting in some parts. Not for anime haters. (Like ToA.)

Generally, all of them a pretty good, although I prefer Tales of Symphonia compared to other Tales games, and Xenosaga III MUST be played after the other two are completed, otherwise, all are solid purchases.
