Resuming from replays, while it would be nice, is a very ambitious goal. There are many security/validation/design issues to consider which stand in the way.
However it seems more doable to simply force the game to repeatedly, persistently reconnect if it detects a connection dropped. Currently, if the wifi drops for one second -- ie. any time someone sneezes too loud, uses the microwave, or listens to Nickleback -- the game drops, with zero chance of recovery.
In my opinion this 'keep alive' feature would be the single biggest improvement possible to the game. I've dropped from countless matches due to flaky connections.. seemingly always at the worst possible time.
How difficult would this be? Currently planned? If so, any chance of it before 4.0? Sorry to nag. I greatly appreciate everything you have done, Deadcode and Cybershadow.
