After I downloaded the Valkyria Chronicles II demo yesterday, I also downloaded the demo for Hot Shots Tennis: Get a Grip.
Honestly, I'm having a better time with the latter. Of course, it looks and plays a lot like the Mario Tennis games--which I adore--so that shouldn't be much of a surprise.
Anyway, the demo definitely has whetted my appetite for more of this game, which I just placed on my all-too-lengthy "to buy" list.
Considering Hot Shots Tennis: Get a Grip costs just $19.99 (order it here), I'll probably pick it up sooner or later--certainly sooner than I'll pick up the $40 Valkyria Chronicles II.
By the way, Amazon is selling the PS2 version of Hot Shots Tennis for just $8.15 at the moment. Here's a link.
