It's pretty good but has some very annoying problems and not the most logical AI. It can be enjoyable for grand-strategy players, although I can't really recommend it to anyone but the rare people who want an unexpected and honestly weird take on strategy.
Fort Solis is a great game with amazing production quality, there are small optimisation issues, and the pacing can feel a bit slow at times, but the story, graphics, and sound design are all amazing. It has fair pricing without a "premium version" or DLCs.
DROS isn't bad, but it isn't good either, the game has a few more negatives than positives, but to be honest, it mostly has "neutrals" and is extremely uninteresting.
The game is great and every aspect of the game is positive. It's not perfect though, having slight issues with the gameplay and story pacing. The good and fun things overwhelm the tiny amount of negative things making this game definitely worth buying.
Space Cats Tactics is very bad and is unenjoyable in all aspects. With optimisation issues that cause the game to crash and a lack of basic features such as being able to save the game yourself, it is not worth playing at all.
The game is pretty fun and is mostly full of positives, except that the story is a huge disappointment after the demos, and there are some puzzles that don't make any sense. It's a unique game and can be worth buying when on sale, but not for the full £8.
The game isn't much fun and has the worst pacing imaginable. It's probably not worth your time or money and you won't be very impressed by anything it has to offer, so there are probably better games to spend these $3.99 on.
