I was looking at getting some roguelikes / lites (already have ToME, CoQ), unfortunately Cataclysm DDA is not on sale.
Krone Hotel at 90% off looks like a decent choice too. Then there’s Jupiter Hell, which I recently stumbled upon and looks great too.
I’d also like to get some of the FF games, though I’ve played VI, VII, IX and a bit of XII, it would be nice to revisit some of the older ones I haven’t played almost since the PSX era.
If you like space games but not grind, grab Outer Wilds (NOT outer worlds, different game). It’s an indie game that’s got a really cool concept behind it and has a really tight, focussed story.
