During Hellfire Comms' 2013 Zeldathon, thanks to some very large (and also many, many small) donations from viewers, $9146.43 was raised for the charity Child's Play. The viewer count was high throughout the marathon, and peaked on the first day with 1000 viewers. More than $1000 was raised on the first day.
This was blown out of the water in the Sonic-A-Thon, where in the first day not only was in ONE donation on day one for a $1,000 donation, they raised at LEAST $4,600 before they finished the first game!
Tom successfully taking out a robber using stealth in part 6 of the Heavy Rain playthrough.
Donnie managed to run Sonic Spinball in the Sonic-A-Thon FLAWLESSLY and beat the game LIVE for the first time without losing a life, needless to say he was ecstatic.
Digital Alchemist took on Shadow the Hedgehog's final boss during the Sonic-a-Thon. It was his first time ever fighting the boss, so he was basically going in blind. Not only did he beat the final boss for the first time, he did it without losing a single life.
On Top of that, Digital Alcehmist finished the battle with less than 10 rings and it was looking like he was indeed going to lose!
