Payday 2 (Restoration Mod) is probably my favorite game/overhaul of all time. Helldivers 1 being a close second.

Mod wishlist:

• Full custom made SV Teto voicelines replacer for Joy.
• On The Road SV Teto cover.
• Break The Rules SV Teto cover.
• Mod that allows you to sprint while crouched but at slightly slower speed.
