Actually for Japan, I blame Idolm@ster. It's the game that made Namco's eyes light up from all the $$$ flowing in. Selling pieces of clothes and accessories and songs for $3-15 each had some gamers spending $400 in DLC on a $60 game. Namco made insane cash.
Then they introduced it to Tales games. Selling dozens DLC costumes for $5 per costume, and accessories and items and xp/money.
Then they started putting it in all their other games. Gundam Musou 3 had like $30-50 worth of DLC characters and I'm sure One Piece Musou will have the same. Plus they're already selling these base games (Tales, Musou, etc....) at $80-100 for just the game itself (plus director's cuts later on).
I am DREADING the day they put DLC into Super Robot Wars. It's one of their big cash cows and heavily otaku based (which is the market that they can gouge hard). But until now none of the SRW games have been on a system that supports DLC. What DLC can you make for a story based single player SRPG? DLC maps, DLC units.... oh god I don't want to give them any more ideas; it's going to happen

Basically Namco have taken over a huge part of the Japanese market. Outside of Nintendo, SquareEnix, and maybe Sega, they have the rest of the biggest brands and so they're on a mission to destroy 20-30% of the market with rape rape prices if you want to play those games

As bad as Capcom is, I don't think anyone would have wanted to see what Monster Hunter would've been like under Namco.
Horse armor is an unbelievable value by today's DLC standards.
hahaha.
