What are the mechanics or game genres that are suitable for pen and paper games which has no erasing (unless you make a mistake).
Game mechanics
No varying status: Ex: Money that goes up and down all the time.
No backtracking: You always push forward
No destruction of stuff in play, rather blocking the player to achieve their task than destroying their previous tasks.
Little randomness: I like the idea of pocket civ to draw 1 card per turn to change the situation. Rolling dices is another other option, but it's not friendly to use in all situations unless using a digital roller.
Game genre
Construction games: Like train games allow constant constructions and tracks remains permanent. Any game that is time-lapse friendly could be suitable. Civilization games could work if there is no destructions.
Push forward: Dungeon delving games and solitaire RPG. Traveling game like Tokaido where you cannot backtrack.
Questccg, I looked at your files, I did not read the rules, but I actually like the idea. There seems to be a good amount of depth too.
It reminds me somehow of dungeon keeper. That could be another game idea where you build a dungeon and the heroes try to prevent it's progress.
Being able to play solo could be another characteristic, but it does not seems mandatory. Still, multi player game could feel very much solitaire-multiplayer unless all players share the same sheet.
