>>26610977We used to use a system called Pokemon Tabletop Adventures, should come up easily on google. It was pretty much a mostly straightforward adaptation of D&D3.5 with Pokemon lore, classes, supplements (for more pokemon focused or like Monster Hunter types of scenarios. A lot of classes were broken, but there was a lot of home brew and tools for players and GMs alike that were accessible.
From PTA, Pokemon Tabletop United came out, overhauling the system of PTA in order to make use of more customizable trainers (like not locking a lot of cool things your trainers can do behind classes). However at times it's a bit too complex, especially for new players, and the lack of focus on classes makes the characters less "ace trainer" and "breeder" and more "person who does this list of things".
Dunno how much support PTA has still, all the stuff should be on their site and forums, but a lot of people moved onto PTU. Both are fun, but you might want to trial run the systems and see what you like and dislike and what to fix.
Generally, for a less rule heavy romp (where people can do really over the top bullshit), PTA is better for game feel if you don't mind home brewing and you can trust the players to not completely unhinge the system by being a Mary Sue psychic who possesses legendaries. PTU is more structured, but that can chafe GM and player alike. If you got a strong GM that knows how to play up the bad parts as fun, you'll have a blast. Otherwise it might be too much.
Also if you're looking for a site to do sessions online, Roll 20 is a good site that doesn't require setting up a server or buying software. You can even import pogs, maps, pull music from soundcloud, etc to make your adventures comfier. I use a combination of actual game maps (like the RSE in game overworld for Hoenn) and maps I put together myself. It takes some time to get used to but it's pretty intuitive to use.
Hope this helps.
