  In order to port a game into gamesCC, the RNG needs to be seeded with the gametxid seed, also events needs to be broadcast using issue_games_events. Also the game engine needs to be daemonized, preferably by putting all globals into a single data structure.
+ 
+ also, the standalone game needs to support argv of seed gametxid, along with replay args
