Have both VP modpack and BAT . Seem to play VP more as i'm mainly into WWII . Compact and very well thought out. Just now getting into BAT in the WWI era and find it a lot of fun. Both are great and easy to install as i have had no problems with either . My nod goes to VP modpack for what it is and ease of installation . Can't go wrong with either.Thanks to all involved to bring us both and for free to boot. Regards,Scott
