i told about the project to some of my friends, they think it would be good if you advertise it right.

you may also publish libraries to developers such as fps library (since you want to make controls same that feels like you are trying to make player feel familiar with diffrent scenarioz). i.e. fps libarary could include movement and weapon system. then every one could use these as base, so most fps scenarioz will have the same feel.
