Games that look interesting to me...
Industria
-Parallel dimension WWII looks interesting
Gamedec
-Solve crimes inside virtual games
Star Dynasties
-Empire builder about the politics vs stuff like resource/troop management
Chicken Police
-Noir detective game, the artstyle is awesome
Ocean's Heart
-2D style Zelda game that looks to be extremely self-aware about itself (at least from the trailer voice over)
Lacuna
-Sci-fi noir detective game, I'm really digging the vibe of it.
Per Aspera
-Just a teaser trailer but looks interesting, I have no idea what the game is gonna be like.
And the biggest announcement in the showcase is that Temtem is a console exclusive for PS5. I personally don't care much about a Pokemon type game but it could be one of those break out hits as SkillUp said it's a much much better Pokemon game.
