1.) Put everything into one file. Apparently people find it tedious having to download multiple files. I think, I like that idea. Makes the book bigger =)
2.) Movement abilities. In the Heist expansion, non combat abilities are handled. Likewise, units need an option to do special movements such as: Dash, climb, jump, drop. All of these work exactly like the other non combat abilities: Select a value from 1-6, roll dice, each result of selected die + rolled die = 7 or more is a success, each result of rolled die <= selected value causes 1 point of stress, each point of stress reduces consecutive rolls by 1.
Anyone must be able to use such abilities.
3.) Exploding 6es. An optional rule for anyone. 6es explode allowing for one more die to be rolled. More Chaos. I love it.
4.) "Protect your friends": If you put a model in base contact to a friendly model lying on the ground, the model on the ground cannot be targeted. The standing model HAS to be targeted instead.
5.) Photos. I need photos. Photos explaining, how stuff works. Photos of cool looking scenery of all kinds of flavours.
6.) "Also players/guests photos, like on BGG.
To show different visions of the game, based on the same rules." (Thanks, Dante TK for the input)
