Need game suggestions for 6y & 9y old

[theukmoog]

When my niece and nephew visit they invariable want to play on the PC.
They've been taking turns at a bit of MineCraft but ideally I'd like something they can play together at the same time.
I have 2 xbox360 controllers so something that uses them would be ideal.

Any ideas?

Thanks all... I already have Lego Marvel and Castle Crashers on Steam, so I'll try them with those next time they visit.

And Sonic & All-Stars Racing Transformed looks like something they'd enjoy, too.

Thanks for the suggestions
