Eidos's strange-looking Xbox Live Arcade puzzle game Geon: Emotions is due out today and will set you back 800 Microsoft points (GBP 6.80 / EUR 10.30).
Billed as an "abstract sports game", working out happens in Geon is almost impossible through traditional means.
"Will you choose to spread fear among the other players, or unleash a wave of bliss over them with the aim of subverting their cause?" says Gamerscoreblog, teeing it up.
"Play to your emotional strengths. Allow your dark side to dominate, or win through speed, courage, and style. You can be the master of Geon, but you must learn to use your emotions to your advantage."
We'd start by downloading a demo to see what on earth it actually is. Which is what we'd be doing if we weren't in Japan trying not to fall asleep.
