Low-level modding in Operation Genesis was unusually easy - you could edit the basic properties of the buildings, techs, dinosaurs and some general stats literally just using Notepad. So if you thought you should be allowed to build more paths, or if a particular research should take less time, or if you wanted to unlock all the excavation sites, you could do that with near-zero expertise and minimal work.
There was a little precedent for that at the time (Total War being a good example), but that sort of thing doesn't tend to happen nowadays. Hell, any degree of modability has become rare, due to a combination of the industry's focus on consoles over the last decade and a bit, the trend for paid DLC, and the fact that AAA games from Unreal Engine 3 onwards are so ludicrously complex that dev teams can't spare the time and money to open the game up to the community.
I'll be surprised if Evolution has capability for modding, whether by using accessible data formats or by shipping actual mod tools. But very pleasantly so.

Edit: just had a google and apparently it won't support mods at launch, although they don't rule it out for the future. Prehistoric Kingdom will though.
Edit 2: just realised I'd already said most of this stuff in a post from 3 months ago. I really need a better memory.
