Mixed bag, with high highs and low lows.

For a mod that seeks to add mobs to the game, alex's mobs is second to none. At a glance, it adds everything from the realistic to the fantastical.

When playing with the mod, it's easy to get lost in the sheer amount of content present. Almost every single of the dozens of new mobs added have detailed behaviors and functions. Populating nearly every nook and cranny of the world, the mobs liven the place up, provide new friends to tame or foes to fight, new gear to acquire and resources to obtain, as well as one boss in the End.

One thing after playing with this mod extensively - it is nigh impossible to play without configs. Whether it be adjusting spawn weights to compensate for regular mobs or other modded mobs, tweaking spawns since those goddamn mosquitoes won't stop harassing me, or just causing noticeable lag spikes upon loading new chunks and simply playing around, I can't give this mod anything higher than a 3.5. Additionally, despite being a touch above the Vanilla mobs, the mod has not updated in nearly two years (the creator is probs js busy), and the last few updates have left a bit to be desired.

Good mod, adds a marvelous menagerie, but can be rough around the edges. Worth a download, but I think you can find better alternatives for the real and the fantastical.
