A must have mod. Beautiful and fun. Well supported/updated - quality throughout.
Without a doubt - one of my most favorite mods for flavor and mobs. The animations and 3D models are superior, the interaction with other mobs from other mods is often hilarious and quite facinating. For example: The dolphins from Water Life try to "save" the swimming/drowning goblins - and end up drowning them usually (while the sharks seem to consider them family). The Dwarves go on crusades to masacre the torch thieving goblins and replant as many torches as they can maintain - providing plenty of drops for the players (if they are careful to not attack any Dwarves in the process). The goblins even trade with players and mount resue missions to free other imprisoned goblins! Simply fantastic.
To top it all off - the developer is very quick to respond to issues and requests - and very active in our MT community - a gem by all accounts.
The only warning/note I have is this: Goblins are messy.. I mean.. really. messy. LOL. They are, after all, pests. They do dig furiously and create a LOT of cobble.. and some if it is trapped! While most of this mod is a passive mob(s) addition, these traps are a light and fun twist - and some of the Goblins will also attack players - but even for un-armored players they are far from a sudden death scenario.
This is my favorite texterpack for production servers - players always compliment it and seem to thoroughly enjoy the experience. It also meshes well with most other mods (in most cases), with little in the way of miss-matching edges or wood types (for example).
