Some may not agree with me and if you don't I genuinely ask you to explain to me why you like this game: Infinite Space.
The gameplay is so confusing it makes Knights in the Knightmare mechanics look like a baby's toy. The characters look blend and unispiring, voice acting is bad, but luckily it's only in the videos, the graphics are just terrible and for the last, the worst, the combat is so boring it almost made me sleep and I'm not kidding.
Maybe I'm missing the point about customizing your ship and all, but I truly wanted it to be good.
I like the game mainly for the story, exploration, and customization. IMO the writing is really good and the characters have good depth to them, especially the main character since he changes a lot throughout the game. Even conversations with random people in the bars are usually interesting and make the "world" of the game seem more real. I also like that the game frequently allows you to make choices that change the way the story unfolds, though the game only has one ending. What battles you fight, what characters join you, what characters you kill, what ships and modules you get, all these things can be affected by your choices throughout the game.
The ship customization is a lot of fun thanks to the tetris like modules you use to modify the ship and the fact that there are a lot of different modules with different effects. Certainly more fun than the actual combat IMO. I'll agree with you the combat is pretty boring, but usually it is a quick affair if you keep stabbing that touch screen to skip the animations (everyone does this most of the time, anyone who says otherwise is lying lol). Of course, I will sometimes watch the animations just to feel cool when I see a whole ton of projectiles from my ships wreck everything. I'd say Knights in the Nightmare has much more complicated gameplay, as the only thing especially complicated about Infinite Space is the ship customization. The game does do a pretty bad job of explaining how to tell what enemy ship is "in front" though so I had a lot of trouble against the first boss because of that. Basically though, I'm saying the meat of the game is not the combat so I don't think it is all that terrible that the battle system is unexceptional. So that is why I like it but I can tell it's not for everyone.
