The structure of Stargate Online Trading Card Game
is slightly different from most other CCGs. Instead of just trying to take out as many of the opposing player's health or summons as you can, you are trying to complete seven missions before he/she does. Each deck contains at least a dozen missions and when it is your turn to play the hero, you put down a mission and try to meet whatever goal it throws at you.
These goals are typically to get as many characters into play that total a certain number of points in a particular skill (the skills are culture, combat, science and ingenuity). For instance, if a mission card has a win condition of 3 cultures, then you need to activate enough team members so that their sum of culture points is equal to or more than 3. Once you have reached this goal, you will get the glyph assigned to that mission and you are one step closer to winning the game.
Where things get interesting is when you play the villain. Here, your opponent is trying to earn the glyph and you have to stop him. You do this by adding obstacle and complication cards to the mission that up the number of skill points he/she needs to meet the win condition.
