I bought Nemesis for the espionage game play. The espionage missions are trivial and the cost is too great. Influence points are used to buy sectors, claim enemy sectors and activate espionage missions. You can only bank 1000 influence points, and accrue on average 4 points per month. If you engage in any economic, research and military treaties, you lose even more of your monthly influence points. I'm usually loathe to spend influence on espionage or treaties when I need those points to conquer enemies.
