The Rally Point: The Battle For Polytopia is this summer's low-intensity strategy game

Strategy games are the go-to option when you're looking for something to really get your brain working. But they can seem unreachable when your synapses are being melted from without rather than through overuse.

Everything does one or two simple things, and statistics are kept to basic 1-4 scales for attack, range, movement and defence, plus a few simple special abilities. It means that turns are never very long, and fights take a little thinking over but no strain or advanced calculation.

There's never too much to think about, never too many chores, and between the cheerful cartoony atmosphere and low-stakes matches, any disappointment or frustration is quickly forgotten.

It's other shortcoming is its somewhat limited variety.
