I recently finished playing Cyberpunk 2077 and was really happy with the gameplay and story. I did not have very many issues while playing on the Steam Deck and actually preferred it over my PC.

Toem was the first game that I played on the Steam Deck after Cyberpunk. I was really looking for a seamless and short experience after spending a lot of time on Cyberpunk and this game fit the bill. Not a lot of replay but it is a game I would definitely get my daughter to play.

Hades is a game that has been talked a lot about and I have had it sitting in my library for a little while. After the short and whimsical Toem, I wanted to mix it up again. Though the game play does seem repetitive, I think that Hades would be a good game to jump into from time to time rather than a straight end to end game.

Toem doesn't look like a game for me but definitely unique
