Model Pack 37 looks good from what I see BUT.....
...I will never understand why anyone puts hours, days and weeks of work into a model pack and then is unable or unwilling to provide more than a couple of screenshots
No matter how good a model pack is, its the screens and vids that actually SELL it.
I (p.e.) didnt dare to buy MP 20 because I had near to no info about the character quality and it was the characters I was after. After the author did put up the whole content into the shop and I could examine it piece by piece I immediately bought it - and did never regret it. I also bought MP 23 only after watching the (extensive) vid several times and I can also recommend it.
So regarding MP 37 I'll wait patiently for more information.....or never buy it
In case you find my grammar and spelling weird ---> native German speaker ^^
