Spelunky, for co-op. I definitely prefer the first game for solo but it only has local co-op. Spelunky 2 has both local and network play but the difference between having a single camera follow the one flag carrier and everybody having their own screens is like playing a different game. Single screen is total mayhem.

Interestingly they seem to have migrated the old votes to this. First I thought the writer had sneakily linked to the Dreamlist so that everybody would automatically vote for NOLF.

Yours is the correct interpretation.
