ignore your wealth, it doesn't give points whatsoever. just buy below 40 and sell above 60. use your bribe card for the good deals pre 1836.
nice, fast paced, intituitive, functional game. just add some mini-bosses or some survival features (like hardcore mode or sth) to it and everybody would love it just a bit more
step 1: try different unit combinations or different tactics and fail
