I'd go with some other game entirely.
I mean, I've got my RC book, and I've still got my Red and Blue Boxes too. That's fine if I feel like some classic D&D.
But for rpg play in general? Another game.
What game?
Man, I can't list 'em all. But at this point, there's so many games out there that it's not like there's a lack. Here's some off the top of my head:
Agon
Angel
BESM
Beyond the Supernatural
Earthdawn
Faery's Tale
Hero's Banner
Heroquest
Iron Gauntlets
Justifiers
Marvel SAGA (card based)
Marvel Universe
Nightbane
OVA
Palladium Fantasy
PDQ games (Ninja Burger, Questers of the Middle Realms, Truth & Justice, Dead Inside, Zorcerer of Zo)
Providence
Qin
Rifts
Secret of Zir'An
Spirit of the Century (Note: it's been released under OGL, but is a Fudge derivative and Fudge had a completely different licensing agreement. Fudge and SotC both using OGL now doesn't invalidate them since the original Fudge agreement pre-dates the OGL)
Wasteworld
Talislanta
The Shadows of Yesterday (has a version which pre-dates the 2nd edition Fudge based one. Also, Fudge use would still be possible without OGL, see note about Spirit of the Century)
Witch Hunter: Invisible World
Sorry none of my games are on your list. With the exception of Savage Worlds, I'm not interested in 'em. Been there, done that, moved on.
Soooooo..... yeah. 4E being OGL or not (or even 3.x for that matter) really doesn't affect my rpg life one whit.
And yes, I do own all of 'em, except Earthdawn.
