Well excitement out of your game will come will come as soon you're able to consider it a game. Basically if you're making a game designing mechanics and systems won't be comparably entertaining as the game itself when you've set up your mind for a game. A quick "fix" for that is rewarding yourself with fragments of the game as soon as possible. Get to the playable part ASAP even with close to no gameplay at all. visually seeing the results and being able to play around with them helps A LOT! I suggest you to see the Brett Victor talk "Inventing on principle". PS : I can't currently provide you with links as I'm writing from my phone. Sorry about that.
Well I have the tile renderer working and I can load randomly generated map into the game. Does that count? Haha
Also I have gotten trello up and running (asana alternative). I really like it and hopefully it will allow me to manage my time better. I also have been looking into the pomodoro technique, have a timer on my phone for it! And the RPG concept looks cool for the HabitRPG site, but it doesn't quite look ready for full use yet.
Also I like trello and promodoro because I can use it on my phone while keeping my internet off so that I can use the 25 minutes (might raise to 30) to code without distractions.
