Hint 1: This mash-up between two franchises let's you single-handedly defeat hordes of enemies, while for some big monsters you may need the help of certain items.

Guessed correctly by LiquidLaser: Hyrule Warriors.

game #23

Hint 1: You probably want Ivan on your starting team.

#24
This game has a pretty redundant title. Something like "Blue Sky"

22 is Command & Conquer.

26 is Civilization 3?

24 is Borderlands 2?
22 King's Bounty: The Legend?

Yes it is.

That it is indeed.

#24 is Borderlands 2, correct. #22 isn't King's Bounty though.

As guessed by LiquidLaser this is indeed Hyrule Warriors.

This cross-over between teh Zelda-franchise with Warriors-gameplay sweetened up the WiiU release-cycle.

This game featured a lot of Zelda-themed enemies, including some big bosses. The boss-fights included the usage of typical Zelda-items like bombs or the bumerang to defeat them. The items also helped to reach more areas on the map or get some treasures. They had also an effect on normal enemies.

This game is just fun, slicing through hordes of enemies, while still keeping an eye to the overall situation to reach your objectives.

There was a later release on the 3DS under the name of Hyrule Warriors: Legends, but this is a game that in my opinion works better with the big screen. So the WiiU-version is my pick. Aside from other Warrior-games that play similar, the Switch now has Fire Emblem Warriors, which in my opinion is good, but not as good as Hyrule Warriors.
