Note it won't look anywhere near as fancy as that unless you bake that AO in your texture.
I personally think the AO isn't needed, it'd be unnecessary
If anything, Blockland should have an ambient occlusion shader with settings for radius and strength so it's adjustable, doesn't require downloading higher res PNGs from the server and wouldn't make the model look out of place in a game that makes almost no use of baked ambient occlusion
Buuut that's just me
Thinking of baked AO, i decided to try it on my Snowmobile real quickly in Blender by using the lightmapped UV unwrap (though the seams are a LOT more noticeable, the sized down image doesn't show them as much)
