Looks like they need to start selling the TITS games for $5. At least the numbers will look impressive.
Numbers for the first game are impressive, and I don't think it has ever been much cheaper than $10 (at least on Steam). It's not like the PSP version was selling 200k in the west.
The second game will eventually sell. It's hard to convince people who bought the first for $10 (many of which never beat that game) to dish out $20-30 for the sequel.
