When I got 'The Orange Box', I didn't really know what to expect because I had never played Team Fortess 1, or Half-Life 1. But I was really suprised about it.
I didn't like Half-Life, but for me it's either you love it, or you hate it, I personally got bored.
But Team Fortess was simply amazing. This game was in production for a long time but was fully worth the wait. Online only but buying The Orange Box for this is completely worth it. It's a welcome change from the other shooters and online games, because it's simply a laugh, although tactics are involved so it does require to get along as a team but everyone I met on there realised that and were friendly. Being an engineer and building turrets to protect your base, or being the spy and running around disguised as the other team was too much fun, and would 100% recommend TF2 to anyone, even if they don't like shooters.
Then there's Portal. Portal is probably one of the best games I have played. It's a puzzle game, and I don't usually like puzzle games but this one was just brilliant. Ask anyone with The Orange Box they will say the same. What I enjoyed most was the mind-boggling gun, shooting at the floor then coming out of the ceiling. The end credits are the most funniest credits I have ever seen as well and CANNOT wait for the sequel.
I completely recommend The Orange Box to anyone as it has everything and is the best bargain you'll come across. Each of these games are worth £40 on their own, but you're getting 5 for £25. What more could you want!
