The colonial game seems like it could use some tweaks:
Scandinavia no longer receives AA - in Beta 9, the Norse and the Dutch were the only ones to receive AA within their waters, but since Beta 10, I haven't seen the resource appear near them. If the Ottomans hold Istanbul, Russia will have an uphill battle to take the Bosporus from the massive Ottoman stacks. Holland is often an easy target (the only catch is hoping you can get the necessary open borders agreements needed for your stack to reach Holland), and sending a settler to Iceland is another easy route (since the Norse tragically never settle it), but capturing the Scandinavian AA is the best way for Russia to play for its goal, and the most historical since Peter's primary motivation in the Great Northern War was to take the Baltic coast from Sweden (since for some reason, no one seemed to want to sail around the Nordkapp to trade at Arkhangelsk - go figure).
Also, in Beta 9, everyone in the game built the trading companies whether they were advantageous or not. I haven't heard the bell toll for a trading company in the last 2 betas - the colonial game is kind of uncompetetive at the moment, since the AI scrambles to build the initial Carribean and Mesoamerican colonies, but then quits when it reaches the trading company stage, leaving all the large or exotic ones for the human player, which all but guarantees the UHV goal for the human. (Speaking of East & West trading companies . . . should these really count as colonial projects for UHV goals, or is this a bug?)
The AI also doesn't appreciate the value of AA resources. When I'm at war, a rival colonial power will pillage my fishing boats, then bombard my cities, then pillage my trade route once my cities are down to 0%. This seems fairly odd, as disrupting shipping channels and supply lines has always been a huge part of naval logistics, and not the afterthought the AI treats it as. The AI also frequently fails to protect its AA during naval warfare (the only time a ship protects it is on coincidence of using all its movement points for the turn).
The AI also trades AA away for pennies. Given the value of colonial projects, one would think the AA resource could be extorted in trade, but the AI places the same value on it as clams or honey. Civs without access resources should treat an AA offer the same way the Khmer treat an offer of iron in vanilla RFC - willing to give whatever they have to get their hands on it.
