To whit, I played From Dust (see video on my post this morning).
Which was exactly what I needed. A nice simple game, with simple quests that lead you slowly through the game. Pick up sand, and put it down somewhere so that your people can climb over it to get to the next place they need to go. Pick up water and put it somewhere else, so that your people can get into what used to be a lake. Pick up some lava and build a bridge across this river. Watch in horror when you realise that the diverted river is now headed directly into your village. Restart your level.
What's nice about it is that there is very little time pressure (so far). In a couple of places I've had to have things ready for the arrival of a tidal wave, but it's not been exactly hard to do that. So I can spend ages wandering around a level, enjoying the scenery, and then trying to get the palm trees to grow over the entirety of the island for extra bonus background details.
It's felt like a nice little holiday, and I actually feel like I have more energy than I did when I started.
Time for bed!
