Topic: Could anyone recommend a selection of Indie Titles that I might not have played

That has a bit of everything you know: shmups, beat em ups, platformers, action, strategy games some of the most fun I've had recently has been playing Hollow Knight Silksong on the Switch 2 anything with that level of quality would be a no-brainer for me.

You can't go wrong with Dead Cells. It's an Action/Platformer 2D roguelite. Probably one of the best Indies I've ever played.

Absolum
Brilliant rogue-like beat em' up.
Can't recommend it enough. From the makers of streets of rage 4 (which is brilliant too).
If you like mashing and beating everything in sight with lots of replay-ability. Online and local co-op too.
Can't go wrong. Well recommended

In my opinion you can't go wrong with these games :

Cult of the lamb
Death's door
Hades
Lost in random
Tunic
