18 (16) – Contra Rebirth
19 (N/A) – FFCC: My Life as a Darklord
20 (18) – “Aha! I Got It!” Escape Game

All of the demos are at the top, so Pokemon Rumble is still in first place. World of Goo is 3 places higher than the previous week. Bit. Trip Beat is at spot #11 if you don't count the demos. That game and FFCC are back in the top 20 after being out of the top 20 practically forever.

I think the demos are working. Don't know how much though.

good to know, that article is well written and good to see devs are happy with it also as they may help push Nintendo into making this permanaent.
