Capcom has just announced a mini-sale for Street Fighter X Tekken content and Mega Man 9 and 10, as well as the release of those DmC costumes I mentioned a while back. The SFxT costumes have a full range in terms of pricing, but Mega Man 9 and 10 are 640 MSP each.
As I've said in the past, I'd wholly recommend Mega Man 9 to just about anyone. From a pure design perspective, it's a hallmark of the genre, and one of my favorite platforming games of all time. With 10, I ended up coming away very unimpressed. It feels like the developmental team lacked the same passion that 9 had, and suffers as a result.
