I am actually working on a 2003 game right now. But sadly, I can only use the default resources. Nothing may be added, because it is for a challenge that Kathis placed.
I have the story already, and a design document explaining the game in more detail. But I will not post any topics until I have some screenshots and maybe a playable demo. After all, this game is not made to be the best thing ever. I want it to be good, of course, but for self satisfaction and for the players' entertainment. So it won't be crappy, or so I hope. I'll try to demonstrate that good games can be created without the need of custom resources. What you need is the imagination, the creativity, the originality, the dedication, and the necessary knowledge.
