I hate badmouthing Soldak, because it's really a mom and pop's kind of developer, and I've really enjoyed their games so far tremendously.
Nevertheless, the main problem I have with Zombasite is that there's no hook. Soldak ARPGs were always weak on the ARPG mechanics, but you put up with them because they had an ingenious concept no-one else had. Depths of Peril had a unique random quest generator, and competing with other, brutal clans + the little short stories really made it a wonderful experience. Din's Curse had an even better random quest generator that tried to overwhelm you, and the hook was brilliant: fight the dungeon or the town gets destroyed; lose your quest-givers and the town is doomed. Drox was a decent implementation of an ARPG in a space 4x. The setting was original for an ARPG, and the race relations, together with the quest system, were pretty good too. However, the random quest chains weren't as compelling since they were just ways to kiss up to factions, and with many ways to win, there just isn't as much tension and focus as with the other games. But I don't think it's too much of a stretch to say that TLF was very heavily inspired by Drox, using Drox's very unique concept as a template (and probably making a lot more money in the process).
With Zombasite, I don't get what the hook is. Sure, it contains both elements of DoP and DC, but it also has the multiple victory conditions from Drox, which I think is terrible for an ARPG, since it robs the design of its focus. It's more a union of the various designs from the past than a particular idea: let's take DoP, and add DC, and then add the goals and factions from Drox, and add zombies to the mix. Without a hook, the game rests on the graphics and ARPG mechanics, and those are never going to win any awards. And let's not forget that zombies are a negative, since applying a zombie setting to a fictional world (especially one where zombies already existed and weren't that dangerous to begin with) looks like you're trying too hard to ride a trend.
