This is not what we have been playing recently.
We have now reached the final castle of Mario Bros Wii. The game has been fantastic, and playing two player is amazing fun. The final castle is a bastard though, so we've put it to one side for a couple of evenings until Julie's stress levels decline, and have started Lego Star Wars: The Complete Saga. It's not as much fun as Mario, but still pretty good fun, and she thoroughly enjoyed taking control of Jar-Jar and jumping off a cliff.
In my own time I've been playing Defense Grid: The Awakening (free demo here), which has is releasing a pair of maps every week this month. Each pair costs 99c (79p) - how can I resist? Damned addictive game (I refer you to the free demo earlier in the paragraph).
