I can't say vision is useless, but it's the second least useful of all the skills (free kicking might be worse). Vision just increases the amount of people you can pass to. It wouldn't be that bad, but there are only 3 people maximum to pass to at 60 (max) vision. Vision should also lengthen the arrow that shows where you're going to shoot.
Sorry for the double comment.... But I notice when you have full energy, you can do 2 activities and have a great deal of energy left. Why not let us do 3 instead?
Chess, use the 1x work rate. It'll save you some energy to train skills or build relationships. Once you get a new star rating, negotiate 'till the end.
Okay, this game isn't that bad. Yeah, it doesn't have flashing lights everywhere or a combo counter, but the concept is really original. Graphics don't matter (much) to me, as any player would agree if they'd played Snailiad or endeavor. So, I'll give this game a good ol' 4/5. Good concept, but needs more... effects?
