I'm a big fan of Tunnels & Trolls. I have every edition published - 1st and
My favorite of ALL the editions is the Corgi printing of the 5e rules from 1986.
Not because they renamed some of the more silly sounding spells (leaving Yessa Massa as is still surprises me when they changed Poor Baby - a healing spell - to Restoration).
It's because of the convenient size (slightly oversized paperback) and the affordable price, even for the time - just under 3 British Pounds.
Corgi also packed many of the classic T&T solos in double titled paperbacks. So you got two solo adventures AND a stripped down version of the T&T rules - enough rules that you could play some sessions with other players with what was provided.
Sometimes I think I'd like a copy of S&W or LL in such a convenient, portable and affordable size, but I guess that's what PDFs and tablets are for these days...
