I disagree, because of one main feature that is still missing.
GWX didn't add or fix what SH3 should have had, which are
wolve-packs.
I'm not talking multiplayer, which gives some sort of feeling of being in wolve-pack, but single-player off course...in a fully dynamic campaign.
But I always loved SH3, and do so even more with the incredible GWX-mod!
