What I Need To Do To Finish My Game

My game will be very advanced, and have a very complicated system. Sometimes, I am intimidated by the fact that I have to write all of the code. My game has a lot of features. My game will have animals, crafting, random terrain, mmog, etc. I have a lot of coding to do..

This is a small insight of what I have to do:

1. Startup Window
2. Username Check (eventually)
3. LWJGL Start
4. Physics
5. Terrain Generation
6. Main Menu
7. Animation
8. Sound
9. Music
10. Block Script
11. Chunk Saving
12. Chunk Loading
13. Weather (eventually)
    
14. Seasons (eventually)
15. Temperature (eventually)
16. Crafting
17. Special Effects
18. Textures
19. Distribution
20. Block Selection
21. Chunk Removal
    
22. AI (Artificial Intelligence)
23. Multi-player
24. Server
25. Chat Box
26. Seed Service (my game uses seeds, so this is a way to keep track of your favorite ones)
27. Day/Night

Well, now you know a little more about what I have to do for my game (indie game). I hope that my game (and also first actual java application....) will work quite nicely. Probably, I will put up a block list for all of the planned blocks. Thank you so much for following my game's development!

Thanks,
Doc
