are you looking for a bunch of cheapy games or 1 game to rock your socks?
A couple heavier hitters:
1) Stardew Valley
2) South Park: The Stick of Truth
Both around $10 Canadian.
Grab bag:
1) Bastion ($2.99)
2) Brothers - A Tale of Two Sons ($1.69)
3) Dishonored ($3.75)
4) Limbo ($2.19)
5) This War of Mine ($4.39)
6) To The Moon ($2.19)
Again, Canadian currency
Dishonored is a bit old but still might not quite meet the low performance requirement.
