I'm a little tempted by Chaos Reborn, but I saw 1 review mention that there's not much to the singleplayer and you need to play multiplayer to really enjoy it.
Eh, it' in the dollar tier. If the single player is even an hour or two long it'd be worth that.
I'll wait until the other two games are revealed before deciding on this one, but before this goes away I'll be grabbing at least the dollar tier.
Since I already own half the revealed games in the second tier (and Mafia 3), anything else being worthwhile really hinges on whatever those two games are.
