Halo Reach capture the flag with a buddy. Game winning point without much time, he got the flag and I picked him up on a mongoose and he was screaming the Indiana Jones theme on his mic as we barely made it back to our base in time. I had to do some great driving. Not sure why it stands out so much.
We also used to beat the Easter egg on all cod zombies maps and since my group broke apart I've always wanted to form another group or something to beat the new maps.
Wife, brother, and I have had some awesome moments in Ark Survival Evolved.
Don't get to play all that much these days... Damn job...
