Go back in time and remind myself that when visiting this thread in the future to NOT read posts 329 and 330.

I'd go back to December 18, 2014, and post in this thread. And I'd say I was going to Stephen Hawkin's party, then say immediately say I wouldn't, which should create enough of a space-time ripple due to someone saying nobody said that they would go to the party. That ripple should, I would hope, be enough energy to push and rotate the core of the earth in such a way that it elongates everyone's evening by 2 hours, which will both solve global warming and provide enough time to either finally beat that long rpg you're playing or finally get the amount of sleep the doctor says you should be getting.

I would go back in time and kill myself, thus making sure my grandfather couldn't exist! Only then Paradox: How I dead when grandfather isn't?

1) Stomp grapes; collect juice; bottle.

2) Fast forward 12 years.

3) Profit!

As long as you don't eat my cookie.

Going back to times shortly after various famous people were born and secretly changing the middle names on their birth certificates to things like Squigglepoof and Hardfartagin.

Going back in time to get a job at GOG, then using staff privileges to lock this topic before HunchBluntley could revive it.

(Except that I wouldn't have known to do this if the topic had been locked.)

Go back to delete this post

Go back in time to before I used the time machine, then destroy said time machine (which would prevent me from going back in the first place).

(If this topic takes off again, somebody needs to go back in time to add the [Forum game] tag to this post.)

Since I just worked out this came to me.

Work out, shower, go back in time to before the initial workout. Get the exercise in but no longer sweaty and lowered my water bill. I'm not a dad but I feel that's the kind of shit that gets dads excited.

Lame, you said.
Going back just a day before my milk expires. Not going back to the (near) future. Too afraid that the time machine inventor might beat me up like a pinata.

For a fee, I will be willing to go back in time to shortly before you install GOG Galaxy to tell you (politely or forcefully -- your choice) that your future self warns you to not do it. (Fee must include any travel expenses and directions to where your past self will be located -- a time machine is not a geospatial transporter.)

Go back in time, and slap a web developer in 2008 for not putting spam controls on their forum software.

Go back to one minute before my food gets overcooked.

Go back one hour repeatedly in order to watch an entire season of a tv series.

Spend hours designing the perfect character in a game, then go back in time with the exact specifications to have it done in minutes.

Repeatedly go back in time after intimate relations to learn the pattern of my partner and forever encase myself as the perfect lover in their mind.

And the lamest one of all in the gaming context, to cheat in PvP. Regular noobs use wallhack, I use timehack. We are not the same.
