Spider-Man: The Sinister Six

A PC game from 1996 that you don't know and probably don't care about, Spider-Man: The Sinister Six is unknown for good reason. It's a horrible game. Very boring and very stupid. The game is part click adventure (as in one part is slightly a click adventure and the rest you just talk to people by clicking on them), part action, and part shithouse.

The levels are ugly, the puzzles are insultingly stupid, and the whole game is just fucking dumb. What qualifies as action is amazingly repetitive and just needless. The closest thing to describing it would be rail shooter, but a lot of it is moving your mouse to dodge things, like a Sonic bonus stage, and even then the game just doesn't care where you move your mouse. No click adventuring (unless you count moving across the room as adventuring), and no action only leaves one thing.

Assassin's Creed: Brotherhood

AC: Brotherhood is really good. The inclusion of multiplayer works surprisingly well, and the plot actually moves forward a whole lot even though the game seemed like an extended add-on to AC2. There aren't any new inventions from Leonardo, there isn't any traveling between cities, and the game as a whole feels like it's being held back to conform with the previous game. This is a very large add-on to Assassin's Creed 2, and it's still fun as the rest of the series. If you didn't find the early Assassin's Creeds amazing, this game won't change your mind. If you did find earlier installments good, then you'll have the same feeling for this game.

Rogue Warrior

A game that had a chance to be good, but botched it so bad. It's one of the worst games I have ever played. The worst game around today. Sadly, it's not funny bad, so don't expect to get that out of it.

H.A.W.X. 2

H.A.W.X. 2 is very... weird. When you're playing it, it seems fine. You fly around and shoot things. Neat. Good fun. Afterward, you'll realize you have no clue what the hell is going on in the story, and feel like you haven't really accomplished anything. You never become interested in the story, meaning you're never vying to find out what's going to happen next. It feels better as an arcade game rather than an actual game with a story. Maybe it's because I never had a big affinity for flying games, but I didn't really like this. It probably didn't help that Ubisoft kicked me out of my single player game all the time too, just because my internet is shit.

Civilization 5

Civ 5 majorly improves on past installments. One game can last around 20 hours if you want it to, and it's fun to build up your city and nuke the neighboring enemy. Although the inclusion of multiplayer is a joke, and very poorly done, playing with bots offline is still awesome. If you're even somewhat into strategy games, you will enjoy this game.

Psychonauts

Psychonauts is a trippy and fun game. There are so many different environments you will encounter through the game, and all of them great. No multiplayer and no side-missions makes this game suffer in the replay department, but the single player is too good to pass up. It's colorful, unique, and a breath of fresh air from the many 'gritty' and 'realistic' games. From taming a wild bull to stomping around a city populated by fish, this game is great.

Moonbase Alpha

While not an amazing game by any stretch of the imagination, Moonbase alpha is hilarious. The developers didn't put in anything 'funny' persay (besides microsoft sam reading chat messages), but trolling and screwing around in this game is great. It's free too, so play it. It's better than a lot of other games out there.
