# I don't like medieval fantasy settings…
Neither do a lot of other players! Many rule systems are relatively setting agnostic; Pathfinder, for example, has pre-published adventures that take place in WWI Russia, one that lets you play as pirates, and another featuring laser guns. Alternate settings such as Ravenloft and Eberron are compatible with the rules and feature entirely different settings. There are also dedicated systems, such as the fairly popular Shadowrun and Call of Cthulhu, that take place in a Cyberpunk setting.
# I can't into roleplay!
Everyone can roleplay! You don't need to be an amazing actor or even a passable one to roleplay, especially if you join a more experienced group. As time goes on and you become more comfortable with the system and setting, roleplaying comes naturally. Experienced players can also help to coax some roleplaying out of shy or uncertain players. Don't be scared to try!
Many groups don't even use voice or video chat, and many of those that do only use it for out of character or combat chatter.
# If I wanted to play, where should I begin?
D&D 5e has the largest ttrpg community right now, but is often considered too rules-light and rather boring to actually play. This same lightness is what makes it popular, though, and it is very friendly to new players trying to learn how to roleplay; the rules are extremely simple to understand and you can focus on the character more than the rules, although it is restrictive and some concepts are not viable in 5e.
Pathfinder is also very popular, and is based on an older, beloved version of D&D, 3.5e. It is rules heavy and sometimes considered difficult for new players because of the high levels of system mastery demanded for optimal play; however, many groups do not play at a high level. Pathfinder is notable for having somewhere between five times to twenty times the content of D&D 5e, depending on how you count, and extreme amounts of homebrew and third party add-ons. Because there is so much content and so much homebrew, almost any concept is viable in Pathfinder, with the right system knowledge to bring it to life. Pathfinder is not technically free, but nearly the entire game system is licensed under the Open Gaming License, which means it is essentially open source and free-to-use. The entire game rules, sans the organization of the books and setting details like gods, is available here: https://www.d20pfsrd.com/
Shadowrun (5e) is a good choice for anyone looking for something besides bog-standard dragons and liches. It is a game that takes place in a cyberpunk dystopia in 2070 by default, and includes cyberware, car chases, and machine guns. It does not use a level system, which can give it a grittier feel than both D&D and Pathfinder.
Fate is an extremely lightweight system that has the advantage of being legitimately free for those averse to pirating, as it is pay-what-you-want. It is not friendly to new game masters, but its simplicity means that it is easy to learn and teach for players. If you can find a group playing Fate that welcomes new players, it isn't a bad place to start.
Call of Cthulhu is exactly what it sounds like, and is probably the system here that has the least ability to be lifted from its setting. It is the originator of SAN points and has an aesthetic that is very rare outside of CoC. This also means that groups can be harder to find outside of dedicated fansites for the game and setting.
