First two things I would be working on are
1) Removing the date checks on events, starting with 1805, then 1806, etc.. so that an early invasion of Austria by France doesn't mean waiting until October for a treaty. HRE could be dissolved after Pressburg. RHC could be resolved after HRE. Limitation is engagement points, which can be tweaked.
2) Providing an open diplomatic system via Regional Decision Cards (or Events). 18 of them would be provided for each power in order to
- 1) give money (say 100 gold) by dropping it on a country capital
- 2) transferring ownership of a region to another power
- 3) give horses by dropping on a capital.
3) With open agreements between players, should the treaty events stay around? My thoughts are yes, and they should NOT require the defeated opponents approval. In other words, Nappy captures Wein, fires Pressburg and it goes off with no choice by Austria. Alternatively, both France and Austria could agree to not do Pressburg and use regional cards instead.
This would enable open agreements, not enforced by the game and unscrupulous players could go back on their word, just like Nappy did.
Thoughts?
