From my experience with the game, if you didn't know where the ball was headed, you're not going to make it to the circle in time.  In general, the circles only seem to appear on slower, easier to return shots.

There is indeed nothing wrong with Mario Tennis's gameplay.  It's rock solid, and addictive as hell.  Unfortunately, the whole package is a bit slimmer than I'd like.  Single player mode is somewhat weak, 3D effects are nonexistant, and the online is smooth but barebones.  6.5 is a bit harsh.  Somewhere between 7 and 8 would have been more fitting.

yeah, but who actually wants that?  3D is a lame gimmick, I've hated the 3D in all my 3DS games, they'd be better without it.  It's just a silly gimmick that eats battery life. 

Speak for yourself.

I do

Depends, Mario 3D is another game when the 3D is off. Kid Icarus also benefits immensily. And I can't wait for something like this (3d puzzles!)

or this

But I agree, it's not necessary, just cool (and sometimes very cool!)

Yeah!... what?

some vita games is only possible on vita. example: how are you going to play gravity rush without the motion sensing controls?

Come on, people, let's try to keep the platform-trolling at a minimum. It's not a bad thread for gauging what the *good* games are for Vita, or at least the good games that people not necessarily interested in Vita itself are interested.

well, 3DS has motion sensing controls. They're just not well known because they don't go well with 3D, for obvious reasons.

Nothing on Vita interests me, but there are some good choices some will enjoy.
