If anyone is paying attention the humble tore is having their spring sale. I know we are a month or so from summer sales usually amazon has one during first week of June and the steam one happens a few weeks later
I've been wanting to check out Spec Ops: The Line for a long time and the current humble bundle lets me do that for a buck. Also The Darkness 2? Also I can see the train wreck that is Duke Nukem Forever.
If all you want is XCOM2 then you just have to remember to cancel before February 23rd. Obviously they're hoping people will be impressed enough by this deal to stick around, but there's no requirement to do so.
