:schutzkontakt is designed towards the engine and my experience.
I could do it alone, with a little amount of money to get some nice animated enemies.
Just like Peter Müller aka anarchie2199 with "MausGame" did.

But I lose the motivation sometimes. This is a normal progress,
no need to worry.
Just play DeusExStalkerHLorwhat and you´ll get your motivation back.

And here, finally, it goes on-topic. (quite subtle)
Because it is your FPS, your passion, your dream, you are the only one who can do it.
If you´re lucky, you´ll attract some helpers. But don´t rely on them.

This makes me think of a community project, which is small.
Remind: Start small. You can´t do Dungeon Keeper with a bunch of nerds,
which never have worked together so far.

Insteat of that, start a really small but modular project.
Examine your workflow, choose your tools. This needs time and small projects.

But I think it´s extremely hard to handle without a leader.
