"My only grudge about SP is that there are no known ways to replicate the exact boss settings has seen on a server and thus makes the whole thing extremely trivial. In fact, you can easily beat the dragon/tek cave with tamed creatures in SP, where bred ones are mandatory on a server."
All you have to do is type this in your game.ini: bUseSingleplayerSettings=False, or you can uncheck it in the general settings before getting in-game, the settings amps up everything for the player, especially their per level up stats, it also gives an exponential buff to creatures' melee %, making them very overpowered. It also completely buffs baby growth rates, for example, it supposedly gives egg hatch speed 16x and baby mature speed 32x. This is primarily due to the fact since your playing alone, they expect you not to want to waste your time on playing official settings, because there is no competition in SP. But, you totally can disable the setting and go to official settings if you really wanted to, this is how I play, but up the settings, like I do 5x tame, 3x harvest, 50x mature, 50x egg hatch, 2x imprint, etc. etc.
Here's where I got most of the information (I knew what it did, but not the specifics.):
I hope this helps answer the thread's question.
