Monolith

You didn't like the DK Retro games?

I mean I really didn't like the motion controls in the Wii version of DKCR but hey that is why the 3D version exists 

I have to go to Monolith. Great amazing games too, but they just do a lot more than Retro.

Nintendo wise, I'd give the edge to Retro as they have made some of the best games to ever grace a Nintendo console wear about some of Monolith Soft's best gems were on non Nintendo console. Non Nintendo wise I'd still give the slight edge to Retro Studios.

Retro easily. Never was a big fan of Xenoblade Chronicles.

Whoa, this is really close, 19 votes each as I write this.
Monolith had a 60% to 40% lead at the start, but they've been neck and neck for a while now.
This should be interesting.

Monolith, I'm a sucker for their Xeno games.

retronolith.

every gamer must experience xenoblade and metroid prime.

Monolith made the best JRPG of last gen, it's not even a competition for me.
