I wouldn't consider Serious Sam: TFE a masterpiece, but it certainly a FPS classic worth playing at least once. Beating this game on the hardest difficulty earns you some major bragging rights. 7.5/10

Half-Life: Opposing Force isn't as good as the original, but it's still solid. It's by far the most action-packed game out of the series. Definitely recommended for fans of Half-Life. 7.5/10

Plants vs. Zombies is one of the best casual games ever made. It's addicting gameplay and charming style makes it a must play title. 9/10

Assassin's Creed 2 is a great sequel. It takes the original game and improves upon it in almost every way. Easily one of the best games in the series. One of my personal favorites. 9/10

Job Simulator is a really good game, especially for newcomers to VR, but the game is simply far too short to justify it's price. Recommended only on sale. 7.5/10

Hitman: Absolution is weird. It's a linear action game with a Kojima plot and a Hitman skin on top of it. It's unlikely to please hardcore fans. However, despite it's many issues, I like it. 7/10

HL: Blue Shift, while decent, is one of the weakest entries in the series. It's clear that this was made by Gearbox instead of Valve. It's worth playing at least once for fans of the series. 6.5/10

Despite it's final chapters not being the greatest, Half-Life is a must play title for any FPS fan. It's one of Valve's many timeless masterpieces. 10/10

While it certainly doesn't replace the original, Black Mesa is a great fan remake. Definitely a solid way for old and new players alike to experience the original Half-Life. 8/10

Half-Life 2: Lost Coast may not win over anybody who isn't already a fan of the series, but those who enjoyed Half-Life 2 will likely have some fun with it. 8/10
