>>30753702No, it's kinda tabletop style, all of us have our own characters and teams.
Pic related was the map for an earlier one (mind you, drawn by our best artist, and that definitely ain't me), we pretty much all started in the lower right corner and progressed through there, through Roll20 we can place and move markers for each character, as well as wild Pokemon and NPCs that appear. This map in particular was huge and took a couple sessions to get through, then the final area was on a different map, and was largely an open battle arena since the boss was a colossus.
It's a very nice site and easy to learn. Different GMs do things differently, but I tend to use damage calculations similar to the games, and you gotta roll for stuff like accuracy and secondary effect, but anyone can choose to use their moves or skills in ways that aren't their normal purpose. In those cases, they describe it and then roll for success, and how high they'd need to roll depends on things like how capable the character would be of doing something like that, how difficult the task is, how much luck it'd require, etc. So a Machamp would have to roll to use Strength to throw a fallen pillar at a target, but would find it much easier to do than something like a Smeargle. Also there are things like making a ground slick with Ice Beam, blocking a cave tunnel with Rock Slide, Digging a hole big enough for others to take cover in, etc.
