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.
FF games are a solid choice. The Pixel Remasters have been very well received and anything that makes the early games more approachable is a solid win in my book. That said, I personally found the 3D version of FFIII (actual 3, not 6) to be phenomenal.
FF Pixel Remasters on SD are an absolute blast.
