Finally reached my limit and switched back to the mod and Epoch. It's ridiculous how wide the divide between the two games is. I gave the Standalone time enough from release til ~2 weeks ago, but there's really no contest.
The most revealing aspect of the difference between the two came from my attempts to record footage and put together youtube videos for each. The Standalone is simply horrible at producing view-worthy moments and excitement compared to the relatively incredibly advanced state of the mod at this point. The lack of vehicles, paucity of zombies, startlingly low variety of weapons, and absence of respawning loot as well as a competent server browser really makes it impossible to go back to standaloone since I've been playing Epoch again. In the three days I've been back and active playing Epoch I've collected an amazing amount of really cool encounters. Hunting players and camping a single location doesn't even factor in anymore.
I know Standalone is alpha, but going back after playing the mod is unconscionable at this point. Standalone needs a year, at least, to be truly playable past the first two months of purchase if the current development pace remains consistent. I'll still highly recommend DayZ to anyone, even the Standalone to new players, but the mod is still where it's at as far as the game itself is concerned.
If anyone's interested in playing Epoch, we've got a very capable squad and a really cool base in the works, and we always love more people to roll with us, even if it's solely to PvP and gather gear.
