Chuchel!

Bioshock Infinite
Band of Bastards for Deliverance

Darkstone has extra random side missions available as another download on the web(dunno if this GOG copy has them)....they might also be worth looking into.

Alas, nothing. Too broke.
Well, Obduction, but it was free.

I'd gift ya a ton of games if I had extra money as stories like that always get to me.

I'd gift myself some games but I feel like there's nothing worth buying :<

EDIT: And I can't really find time for games..

Buy a time turner.....I hear the Wesleys sell them all the time.

So far...

Fear Effect: Sedna
Grim Dawn
Curse of Monkey Island
Escape from Monkey Island
Diablo + Hellfire
Pillars of Eternity II: Deadfire - Obsidian Edition

Waiting for the following at a good sale price...

Bard's Tale Trilogy
Forsaken Remastered
Cuphead

Obduction
Toonstruck
Dex
Star Wolves (the first game)

Affordable.

Day by day, I gazed upon Quake 1 and 2.
I'll probably end up getting it by the end of the sale, can't be bothered to wait another couple of months to see if the sale price goes back down to 66%.

So far I've only purchased a few games (low on cash).

- Slime-san
- Pikuniku
- Tsioque

- Redneck Rampage to dabble with the Rednukem source port.
- Renowned Explorers: The Emperor's Challenge to complete my collection.
