[blush]I've never been called out before![/blush]
What I do depends upon the totality of circumstances.
I've been gaming for nearly 30 years, and while most of the gamers I've gamed with are open to new RPGs, I've encountered a few who are single-system players. Sometimes its some form of D&D, sometimes its GURPS or HERO.
Currently, I associate & game with about 15 gamers...most of whom are in a single group currently going through RttToEE. Of the 15, at least 2 are D&D only...but for different reasons.
One claims to simply not have the time to invest in learning a new system. IMHO, she's no busier than anyone else, but she doesn't manage her time as well as she could...so I give her a pass. If I want to include her in a game, I'll run D&D, but I don't feel any particular loyalty to including her. If she were the only one to object to joining a campaign because it wasn't D&D, I'd still run the game and let her be the one to decide whether to show up or not.
The other is merely obstinate and unwilling to learn a new system, but I've gamed with him since 1984- he's a pretty good friend. (Usually.) He's also a good gamer within his narrow tastes (virtually Wizards Only as long as I've known him)- if you looked at one of his Wizards, its optimization would be immediately obvious. Part of that is because he's a math whiz- he naturally gravitated to choosing the optimal spells & feats in the game. He's also one of the 4 people who host our large group (as am I).
Excluding him from a campaign is difficult...however, I'm willing to do that as well. He does have other interests, after all, and he could make good use of the time to indulge in them.
The problem is that there is almost no point in trying- several of the other guys in the group, while not actually averse to playing other RPGs, are disinclined to do so because of their very real time constraints...and a LOT of online gaming. In the 10 years this group has been gaming together, the only other tabletop RPG played has been RIFTS...and that only lasted about 6 months. When the guys were into City of Heroes, I volunteered to run a superhero campaign. One guy expressed real interest, one expressed marginal, conditional interest ("I will if others will")...and the rest read my email without response.
I'm not entirely disheartened by this. I still design campaigns and adventures for other RPGs- I have 7 in the works stored on my PDA, covering modern fantasy, supers, sci-fi and other genres. Someday, I'll get a chance to run one.
And despite my frequent posts to this thread (
http://www.enworld.org/showthread.php?t=102706&page=3), I simply don't feel up to running a classic fantasy campaign these days- I'm somewhat burned out on it. Thus, right now, I'm not even running a campaign. I haven't for more than 2 years.
...but I have a
doozy in the works.
