A few Mods that makes some collecting-achievements much less grindy.
Especially bugcatching + fossil-, action figurine- and armor-collecting.

If you activate them at your game´s beginning you should be able to get all the grindy achievements after around 100h.

Achievements will be easier:
Them Bones - Collect every fossil
Armour Aficionado - Collect 210 unique pieces of armour
Mint Condition - Collect 50 unique action figurines
Bug Free - Catch 42 unique bugs

Without Mods i was able to find 2 action-figurines in 50h. And we need 50 different for the achievement.
With Mods i can find nearly one figurine per hour. Bugs are much more frequent. And read in forums about some bugs are "buggy". The mod should fix this and you can catch them now.
You are able to craft all racial armors from the game and no need to trade/find/buy them. You have to gather tons of material to build them all but better as normal.
And last but not least you can see directly which class(small, medium, big) the fossil is before you dig it and no need to waste your brushes.
