Day 24 - Your first video game
Sonic the Hedgehog 2 was the first video game that I can ever recall playing. It's hard to believe that it still manages to be my favorite game that I've played, but maybe the fact that it was my very first is part of the reason why (that, and it's incredibly simple and fun).
Day 25 - A Video Game that had the best mechanics
Both Portal and Portal 2 had the great innovation of the Portal gun to solve your missions, and I personally think it's one of the best game mechanics to date. Considering using the portal gun is basically the only thing you can do besides move around, yet the game was not only successful, but its sequel was too, showed that it really was an outside the box mechanic that worked incredibly well.
Day 26 - A video game that had the best voice acting
It may not have had the very best voice acting, but nothing else is really popping in my head other than Mass Effect 3. Seth Green, Martin Sheen, Yvonne Strahovski, Freddie Prinze Jr. and even people like Buzz Aldrin had speaking roles in the game, which is a pretty talented cast of people.
