Can I just talk about Luigi's Mansion 2 again? No wait, I already did that. A million times. Actually, this weekend I'll mostly be playing Super Metroid and a cool new iOS puzzle game called Stickets. What are you all planning to play this weekend?
Stickets is really simple, but also really, really hard. It disguises itself as a standard Bejewelled-style puzzler but actually features a truly original, sophisticated rule set that forces you to essentially unlearn everything you thought you knew about puzzle games of this ilk. I thoroughly recommend it. Do a quick search for it on the iOS store. I've been playing it for the last day or so -- my record is 79. Which is a bit pathetic!
I might also get round to playing Fire Emblem, or maybe giving Donkey Kong Country Returns a second go on the 3DS. I loved that game so much on the Wii, I think it deserves a second playing through.
