For those people that think Linux users are less likely to pay for decent software … take a look at this:
Effectively you pay whatever amount you like for the “Frozen Synapse” bundle (which includes bonus game “Trauma”), but if you pay over the average (currently $4.65) you also get the “Frozenbyte” Bundle, which includes 5 games - Trine, Shadowgrounds, Shadowgrounds: Survivor, Splot, and Jack Claw.
(also includes a Steam key)
The amount users chose to pay/donate (by platform) -
Windows users - $3.40
Mac users - $5.90
Linux users - $8.78
This would seem to suggest Linux users are willing to pay more than twice as much as Windows users for decent games 
BTW, this offer is only available for the next 11 days 9 hours 30 mins (at time of posting) … so if you’re interested, be quick
