I have 2 tama connections and I have them play games together a lot. I noticed that after several games, one tama kept winning over the other one. I checked and their weight was identical and both had all their hearts filled. Well, I went to change the time on the one that kept winning- after that the other tama that was once losing kept winning. I haven't had time to run any finalizing tests.... but does anyone think it's possible that the difference between the heartbeats has something to do with who wins and who loses?? Just thought that it was interesting.... ^_^
