I've never bought an XP booster myself, and I feel some of the same conflict. Although I can obviously afford it, I don't think I could stomach doing this for new releases. So at most it would be something where I'd be interested after 2-3 years when all the patches are in, bugs are fixed, and review consensus has settled.

So rather than pay US$70 today for a buggy, grindy new release experience, I pay $20 in two years for the base game + $10 for the "player's digest" mod.

I expect even then it would be a tough sell, particularly having to be on PC— a lot of the market for this kind of thing would more casual console/mobile/streaming players.
