Make speed games 3 minutes from 5. Speed games don't need to be 5 minutes, in freestyle or sequential. 3 minutes is plenty to do your move. In freestyle, people usually wait the entire time anyways, and would only need about a 1 minute turn max, however I realize some people like to strategize more (however please put emphasis on the fact these are SPEED games, not casual). In sequential, playing 8-player sequential games can take hours.
So what happens? People who play sequential join a LOT of speed games at once because they don't want to wait. Therefore they consistently are jumping from game to game, making people wait even longer for games (thus everyone joins multiple games at once), and no one is focused on any particular game. People who are focusing on one particular game often have the game ruined because the others don't have enough time to recognize the map and determine the best possible action, they just deploy and attack whoever quickly to get a card, then end. I've had it happen numerous times.
Freestyle is self-explanatory. No one uses the first 2 minutes anyways. No one even uses the first 4 minutes. We don't need 5 minute turns.
This will improve the following aspects of the site:
People don't have to wait as long in games, and in sequential will be able to pay more attention to the games at hand, thus not ruining the game for others. I could care less if they can't handle the games themselves, but it's ridiculous when others just are in SO many games and then just do whatever. Games would move along quicker with 3 minute turns so anyone who wants to argue they like having lots of games for lots of points all at once, it's the same concept. You'll finish the games faster, and you could still have 2 speed games open at once.
