I’ve no idea what that means, either. Could you translate for an idiot who doesn’t speak art?
Taking you at your word (if you're taking the p*ss I'm sorryfor being po-faced, but I didn't pick it up . . .):
Elevator music is meant to make you feel calm and undisturbed. It's meant to be familiar, and to evoke the familiar. Now think of some music that's the opposite of that (say, Stravinsky's Firebird, or to use a more rock/pop example say Pink Floyd's Saucerful of Secrets) - that would count as an
incitement in the musical context. It's meant to provoke a response from you that (i) you wouldn't expect or anticipate, but that (ii) comes from in you - the music is the prompt to a response but not the response itself.
The same contrast in visual art might be a "chocolate box" illustration compared to The Raft of the Medusa.
(Of course over time things that were once incitements become assimilated and part of the familiar. Eg most of the impressionists' work. Much of Wagner. I hope my examples are sufficiently non-assimilated to do their work!)
Czege is saying that these RPGs are incitements like that. They won't make you feel comfortable or safe in any straightforward sense. They'll make you have to confront yourself -
what do I like? what do I think about this? what do I want out of this? - and to get them to work - that is, to play them - you'll have to answer those questions and engage with the games by bringing your creative self to bear in ways you didn't expect. It's the stuff in the previous sentence that is the
believing in yourself, and that Czege is contrasting with (what he sees as) typical RPGer consumption.
I don't know how well you know Czege's RPGs. I've never payed My Life With Master, but know it by reputation. I've read Nicotine Girls and been influenced by it although I can't imagine playing it. And I've read The World, the Flesh and the Devil but again have not played it. These games are all attempts to break away from "mainstream" or "traditional" RPGing - for instance, My Life With Master and Nicotine Girls are distinctive for having a thematic/story trajectory built into them.
So it's not surprising to me to see him enthusing about these RPGs, nor to see him doing it in the way that he is. I think he's pretty self-consciously in the avant-garde of RPGing, in the full sense of that term: ie not just at the forefront in terms of technical design, but at the forefront also in terms of the cultural experience and cultural values that RPGing can be associated with.
