I don't see Out of Space on here. It's pretty fun and challenging.
Goat Simulator is silly fun, especially with kids.
Lara Croft and the Temple of Osiris is awesome since it lets you play up to 4 player co-op.
Vicious Attack Llama Apocalypse is a good co-op twin stick shooter.
A kitchen sink. Did an impromptu kitchen reno due to a gas leak and being without one is such a huge downgrade in quality of life. I was washing dishes in the bathtub nightly and it was absolutely miserable. I don't think I've ever been more appreciative of the technology of modern plumbing than the day I was able to rerun lines to the sink area and get it all going.
