Planet Oat has some tasty varieties, I’m a big fan of their Blueberry Oat Crunch. Also, Dole Whip is dairy free as well and is getting more popular just about everywhere.
Otherwise lactaid is always good if it helps you at all and you still want ice cream.
The GameCube, Wii, and Wii U all use the same basic setup: PowerPC G3 CPU and an ATi/AMD GPU with an upgrade each generation. They are, in effect, very similar to how the PS4 and Xbox One started their own current trends. In fact, the Wii U can run GameCube games natively with some effort, and Wii games out of the box.
