Wait or Play?

I've already pre-ordered Borderlands, which looks like an awsome game, with 600,000 weapons

Or should i cancel my order and grab a copy of Left 4 Dead, which looks fun

Which is the better value?
*comments?*
EDIT: Borderlands doesnt come out till late 2009

Screw them both and get Far Cry 2.

Anyway, I don't know if Left 4 Dead has online or not, but if it does, go with that since online always gives awesome replay value. If it doesn't, go with Borderlands since that game looks sweet.

They both have Online Co-op Play

Left 4 Dead isn't even out yet IIRC...

It's a steam game, like the stream of zombie survival mods for HL2 out there, but this one is standalone.

Only 4 players at a time though, so it isn't as big as some other ones.

They both have On-line Co-op, with a limit of 4 ppl per seesion
