Oh that is a bit of a Killer bundle. I am in just for Blacksad for €4, its never been below €13 before.
Out of Space is a fun enough co-op multiplayer mayhem game like Overcooked, you have to clean up a space ship, cook food, beat aliens and such. There is a lot more to do than Overcooked and I found it all a bit too much work but some people really like it, especially if you are on voice chat/socially distanced couch and can talk and plan.
Railway Empire is a good railway building game, lots of traings, good graphics and decent stab at Railroad Tycoon genre
Tower of Time is a very good RPG with turn based combat. good story, decent graphics and quite a good combat system. It is hard at times though and long, took me around 31 hours to complete without hunting things down too much.
Battlestar Galactica Deadlock has a steep learning curve but a very good strategy game once you get into it. Some people say you may need some of the DLCs to really get the full experience.
Planescape: Torment: Enhanced Edition is the weird Baldurs Gate and they appartently did a good job with this edition. Be prepared to read a lot.
