Text games are ran in a few different styles or ways on Roll20: There are live session games which are played similar to a voice game but instead of speaking, you just type what you want to say or do such as "Torg runs at the orc while screaming and waving his sword" or even longer. How much or what you type varies from gaming group to gaming group. There are asynchronous text games and there are two forms of them on roll20. People with variable work schedules tend to prefer or play one of these styles. Play by Post or PbP : These are usually forum based and all the roleplaying is posted in the game's forum while the dice rolls or mechanics, maps, and character sheets are contained inside the actual game. There are games of this type that use Discord for the RPing and Roll20 for the mechanics. These types of games are the slowest usually but sometimes they can be as fast as live session games. These types of games also run nonstop which means they are active 24/7 as you post whenever you get a chance and is appropriate to the scene. In game text games : These are usually ran very similar to live session or voice games but the pacing mirrors Play by Post games. You log in and enter the game itself, read any new post made, make a post or roll as needed or appropriate, and relax. I host a text only community on Roll20 called Knights of the Written Word 2 and we function as a focused LFG and support group. We have games listing in our forums that are text only, there are threads of discussions about various topics, and we have a text based discord server for live chats (many members use their phones for chatting). I have the link to the community in my profile.
