@Wretched There is a difference between "Wrongfun" and "Not following the Rules" or "Not following the Theme". A game generally has a set theme, that theme enforces a set of rules by which everyone has to follow in order for the game to follow a reasonable path. The part that people tend to forget is this:
Not all games are meant for all character types.
Not following the rules on Wyrd (the example used above) is to me just as egregious a problem as trying to app a Space Marine in a low fantasy setting.
When you make a game world it has a theme that needs to be followed to be part of the game world, such as: No guns, No space ships, No time travel, No Magic, No whatever. People need to follow that in order to be a part of the theme of the game.
I see this a lot on roll20 and D&D games, people wanting to app special snowflake races and classes that aren't part of the main books even when the DM says: I am only allowing stuff out of the players handbook.
Honestly, if a prospective player can't be assed to follow the rules that are clearly written then imho they don't need to be playing on the game. Which segue's into another gaming 'truth':
Not all games are going to be fun for everyone.
If a game doesn't match up with a players idea of 'fun' then the game isn't meant for them and they should be reasonable about that fact and either try and find a game that does match their idea of fun or try and come up with a fun character that /does/ fit the world.
Right now I am /fiending/ for a crunchy Super Hero game. I'd love a game based off Hero System, Savage Worlds, Aberrant, DC (Mayfair games version) or the like but they are few and far between. The only HERO system game I know of has jumped the shark severely, the only Aberrant game I know of has a tiny player base and the XP is very fast so new players literally cannot compete, the others don't exist to my knowledge. So I am left with trying to find something that works for me on those games that do exist, or not playing.
