First off I want to recommend this game. Now If you can, wait until Christmas time and you may get this game for free. It’s been free at Christmas time for the last two years. However, I wouldn’t have any issue paying full price for this game again. Even with as old as it is, I still play this as much as any other game I purchase. It’s challenging, you never know exactly what to expect, the servers are still decently populated with people ranging from first time players to expert ♥♥♥♥♥♥ bags, the graphics are good and I can run the game maxed out on my laptop! If you want a good game with a remarkably high replay value, get L4D2. Don’t waste your money on the first L4D unless you want achievements, this game comes with the first game’s levels ported in. Goodnight America!
