I dunno how CataDDA can get boring; the sheer simplicity and a broad choice of very powerful items and weapons are nothing short of a death trap. If the ‘Pain’ variable governing your character’s ability to move and act was just slightly more punishing, all the zombie kids would be laughing when you enter the Cataclysm. Zombified horrors rule the urban areas whilst natural predators along with ethereal monsters, in and out their corporeal bodies pose a myriad of threats throughout the open spaces. Seeing all this, roaming bands of undead abominations behave as a considerable challenge on their own, especially when you stop paying attention to that stamina stack.
In more recent builds, there is a Zombie Master or a few Necromancers at every road intersection. Even if the possibility of you getting cornered by the army of ever-raising dead isn’t enough - meaning you could manage to escape somehow - a Zombie Hulk is willing to chase you through entire city or town blocks, eating through fences, wrecks and vehicles as the game was Pac-Man, not CataDDA.
If the abovementioned isn’t enough, consider the possibilty of an anomaly on the generated map. For instance, the recent character I introduced into Cataclysm had to deal with two fungal blooms in the spring of the first year. The fungs spread rapidly, draw out Zombies and cover both the roads and plains with fungal beds. Because I had to act quickly, fixing him up with a ride to aid in torching up that hell-spawn machine, it was no problem to keep exploring the map in order to find if there is a greater danger just around the corner. Guess what? There is a dozen of Megastores throbbing-full of upgraded deadZ and, of course, a Fungal Tower nearby.
To put it bluntly, I don’t dig your lack of interest because of CataDDA’s “vanilla flavor”. The only, and that’s one and only time this game got easy for me is when my character got the best possible streak of mutations after completing some pretty advanced surgical attempts to enhance his body bionicaly. Usually, I just get to lead this buzzing hero-wannabe with bulgy eyes and a sharpened stick.
