I agree with Smugglers over Hermit. Definitely Baron.
Festival and Cache are both good options on $5 I think. I might go Festival early then switch to Cache's. I like having the option with Festival to buy Estate/Estate or on $6 Silk Road/Estate, depending on the situation, and the fact that it reduced the (albeit, small) chances of being unable to play a terminal.
I think playing this game would be tricky to time when to build and when to green.
