Recently returned to the game and decided to do an inventory my characters (24...). Since I started playing on day 1, I thought I'd track down my first creation. So, started by looking for old characters who had Batman Inspired head style unlocked, I wouldn't have unlocked it for those particular characters so they must have been from the original FB offer. Several fit that, so looked for the Joker Jetpack, Ninja Climbing boots and Speed Boots - no closer! Finally, I looked for the oldest mail sent - the oldest I found was 4,346 days (approx 11.9 years) but there could have been earlier ones, I guess. Do any of you tech savvy wunderkin know if there's actually a way of finding out? Cheers geez!
You might want to try checking your feats, maybe the "use the Breakout move" feat in particular. Any feats you might have gotten while making your way out of the Brainiac ship after creating your first character have a good chance of giving you the date that character got the feat, thus giving you more info to work with.
Feats/headline section is a good indicator. There's the one for making it off the Brainiac ship if I remember right. This allows you to pinpoint more accurately, as it has a date/time on when you unlocked it.
Yup, as others said, feat menu is the best. I always look at the lowest block break feat, or hit counter feats. Those usually are within the first few hours.
You, good sirs, are gentlemen and scholars! Guess what I've been doing? By cross referencing your advice, I've managed to date my oldest character to 15th January, 2011. Tell you what though - it's quite exciting, finding out how old your main is gets you going! Tell you what, I think there's a business in this! Celebrate your character's "IT'SABIGSCARYWORLDOUTTHERE DAY"
It's a shame you've probably missed all the birthday cake slices given during yearly anniversary events in recent years.
