What game franchises and games need to sell more or need to be a success?

Games that deserve and need to sell more, off the top of my head

Dark Souls - innovative and hardcore, too much good to say. So fantastic it's crazy. 400K for X360 version is very sad.
Vanquish - Over the top humour and great gameplay mechanics. Sadly it sold so badly we won't get a sequel.
Castlevania (the new one) - a prime example of a beautiful, epic and long adventure game
Deus Ex Human Revolution - highly praised, yet only 2 million sold and barely broke even
Dead Space series - better than Resident Evil yet sells only a fraction of it
Enemy Territory: QW/Brink - very misunderstood complex objective based team gameplay
Mount & Blade - a PC masterpiece destined to be niche
STALKER series - deep FPS as it should be
Two Worlds series - great open world RPG that gets shunned because of lack of polish and low production values
Risen series - great open world RPG that gets shunned because of lack of polish and low production values

Since the OP used Uncharted as an example of a game that needs more success I have to react. The Uncharted phenomenon (the game and all the praise it gets) is a disgrace to gaming. Uncharted is a very dumbed down Tomb Raider that plays by itself like an interactive movie. Its success is bad for gaming because all this bling is tricking gamers into thinking it's a good game. It's entertaining for many people obviously, but it takes so much away from gaming without people even realizing.
