Also you never stated some of the strategies you used for this tutorials.
Me and Chess have a strict PD/Imp China rule.. where we tend to just spam inf and take the whole of china and move westwards or eastwards.
MoS Germany is a bit out of date in my opinion. There are so many countries that could counter it in Europe (imo again) so I would recommend you going MoS UK (15k+) with 100+ and without 100+ Uk MoS 10k works good too.
Best country to use in a world game imo is Turkey. Go Imp turkey with any fund (obviously not 25k or 50k), and spam inf everywhere
Expand quickly though. Don't just stack units into 3 main countries around it (bulg,romania,greece) because thats the noob expansion.
