FPSC already supports 1280x1024. Look at the setup.ini-file. If it isn't already there, add the lines Height and Width under the debug category, if I remember correctly.
In order of desire, I think we need this;
1. Better framerate. If possible, a timer-based engine (it would probably require some editing of the weapons and such, as they're optimized for the frame-rate cap, but I'd be willing to pay some few extra bucks for it.)
2. Dark AI. Looking at X10, it sure seems like you can achieve better results with Dark AI alone than you can with a heavy-duty X9-script.
3. Ragdoll physics. As this has been mentioned by Lee some time ago that it would be implented into X9. I can hardly wait for the day I see it in action.
4. Shader update. Update the shaders to work properly with Dark Lights, and make some adjustments for esthetical improvement, the current shaders in X9 look rather unrealistic... The only decent one is the bumpcubereflectalpha-shader. Maybe use the same system as the one in X10? In theory, it seems to me like it wouldn't be a too difficult a task to backport the shaders to X9, except having to optimize them for shader model 3, of course.
5. Dynamic shadows! Be it hard-edged stencil shadows, or blurry soft-edged shadows, this would improve the overall look of FPSC games greatly. I'm not expecting HL2: Episode Two-quality dynamic shadows, but some fine-tuning and bug-adjustment of the current, hidden shadows that are in X9 would be great.
6. Finally, Dark Lights improvement. Introducing spotlights and directional lights to FPSC would make it tons better. Possibly a proper installment of sun-light would also be a great addition. The hidden sun-light feature in X9 had me really excited, until I found out it was about as finished as the dynamic shadows...
That's the order of priority I'd throw the features into FPSC. I do not know from a programmer's point of view which one's easier to implent, but I hope they're all realistic wishes.
