Book of Demons is a fun Diablo-like game, but some of the mechanics might be a turnoff for others. Movement is locked to set paths while enemies are free to roam around and there is no equipment as cards represent spells, items, and artifacts in the game. That said, there is still quite a bit to like about Book of Demons as there is a good amount of strategy to employ if you want to survive. However, the price tag might be a bit much given the restrictions some of the mechanics place on you.
Borderlands 3 is a great game, but it's definitely got some technical issues with sadly brings the score down a bit. While my issues weren't as bad as others I've heard about, they're still annoying at times. However, if you can get past that you'll find a game that's more of the same as previous games (especially 2 and pre-sequel), but that's what made Borderlands great to start with. A great story, reuniting with old friends, and some pretty interesting villains ensures I'll be coming back to open any more vaults that are found on any planet Gearbox wishes to travel to.
Torchlight II is as fun on the Switch as it was back when it launched on PCs seven years ago. The controls on the Switch feel pretty good and eased my worries about transitioning from PC to console. While a lot of the game is basically fighting enemies, collecting loot, and repeat, if you're into games like the Diablo series you should enjoy Torchlight II, and at a third of the price of Diablo III (at least on the Switch), Torchlight II is a great alternative.
Damsel is a fun arcade-style platformer/shooter/speedrunner/whatever genre you want to call it. The comic-style motif is a nice concept that I haven't seen for a long time and the gameplay is pretty fluid. The darkness of the stages and the similarities between the three game modes kind of bring the game down a little, but it's still an enjoyable outing for the Nintendo Switch.
Million to One Hero is a well-polished game in the "custom level creation" genre (is that a genre…well it is now). The controls are fluid and you'll have to employ a lot of skill to finish some of the creations players can come up with. The level creation itself is pretty robust, though it would have been nice if some of the icons were a little bigger on the screen, and combining levels into a mini-adventure is a nice touch. If you're a fan of 2D platforming and level creation, you'll find a lot to do in Million to One Hero for a satisfying price.
