The only mod I really care for right now is a mod for increased tree and grass draw distance. Anything other than the common trees is drawn rather close and if you get a view from a big hill or such then any open plains tend to look very gamebryo

Other than that maybe a few increased immersion mods. Perhaps a mod so you need to eat and drink to survive (kind of like New Vegas) and a mod where not resting in a bed causes your overall stamina bar size to decrease day by day. I know they are not to everyone's flavour but I would go for them. May have a go at making them myself if they don't appear in the coming months

I for one will always play it vanilla before modding.

The craftsmen at Bethesda deserve it.

@limewax Change of tree, grass and objekt draw distance is easily done by editing the ini files. First thing i did. U can change the Lod as well, and tons of other stuff too.
