Although Star Horizon could really use some more levels to stretch out its short story, if you are generally OK with on-rail space shooters, this game is generally OK. I can't say it is great, but it is a good game and should keep your trigger finger happy for a few hours.
There would be a good story to be had if Tharsis was developed to involve more than just trying to survive a few rounds. The theme of surviving on a spaceship and figuring out how to keep everything—and everyone—together should make for a good game. Unfortunately, Tharsis fails on too many points to be really worth playing.
Sisters Royale is a colorful, tongue-in-cheek take on the classic shmup format. On the upside, you get to play through the game as five different player characters. The down side is it doesn't take very long to play through, so the replay value is in trying to beat your last score and to run through the levels on harder settings.
If you like a puzzle game where patterns and timing are critical, then you will like Cyber Protocol. With 100 levels to keep you busy for many hours, it's a pretty good value for the money (especially at the sale price of $2.99 at the time this was published). If puzzle games with picky timing and perfect patterns frustrate you, however, then you may want to keep looking. You've almost reached your decision gate and I can't spare you any more time. End of line.
The graphics, the driving mechanics, the tracks, the vehicles, and the play time in Asphalt 9: Legends are all very good. The game is fun to play and challenging enough to keep the player engaged. However, the micro-transactions and some frame-rate issues do interfere with the overall experience.
Star Wars Jedi Knight II: Jedi Outcast is a bit of a grind at the beginning, but if you can endure the first part then the game will open up into Jedi Force battles and light saber combat which will make all the Star Wars fans happy. For the cost of the game (currently only $9.99), it's worth putting in your rotation.
