Are there any 3D games I could clone as I'm just Getting used to UE4 and Need a Project to Get Me Started

Hi I'm a beginner to blueprints and programming in UE4 and want to produce a game in the next 3 months. I'm getting used to the blueprint system and making mechanics but don't have an idea or goal. Any simple 3D clone would be a fine suggestion. I don't really want 2D that much. So just any simple, small 3D idea/clone would be good, thanks. Hope you leave a comment.Thanks
