I guess. mechanical hints:
1: rpgmakerish (maybe actually). often meta puzzles, no combat.
2: isometric brawler, but you get turns sometimes.
3: physics-based side-scrolling shooter. very few weapons, slow projectiles, crazy vehicles.
4: stealth side-scrolling shooter. clear hotline miami-influences, but with slower and tougher enemies so you're constantly worried about ammo.
5: sometimes you have to make things, and you're not always told precisely what. you have a list of recipes, and you click buttons with your mouse to match the recipe. if you match the wrong recipe, the story progresses regardless. the only resource is money.
