I suggest to keep an eye on heretic operative and spire of sorcery !

Checked the trailer, seems good , though its more of "your secret organisation/nation/country/cult versus the world" rather than "influence existing nations for your own gain". A ridiculously funny game is Evil Genius. Its a bit old by now but its well executed and MOST IMPORTANTLY it's HILARIOUS.
