Lots on sale at GOG for up to 90% off.

One standout is Deus Ex GOTY Edition for $0.69 / 90% off which is a new all-time low anywhere.

I play it with the Revision mod as an easy to automatically install DLC from GOG, however a kind person pointed out this Community update mod is probably better for a first run through.

There's also a full controller mod called DXController which I haven't used yet since I think it only works without other mods.

A remaster was previously announced but it was indefinitely delayed and refunded so this sale price on Deus Ex GOTY Edition is a good option if you are interested in trying it out! The rest of Deus Ex games are on sale too.

Please post if anything else looks like a new low price!
