Talisman Prologue is at 33% off for Europeans it means it’s either 6€ or £4. You can grab it here. It’s DRM free.
Also Of Orcs and Man is on sale too, for about 20€ or £15, I have no idea if it was any cheaper on Steam Holiday Sale but if you want it’s now 50% off. It’s not redeemable on Steam just like the other game above.
