This game is very fun with a good story, but the graphics are dated. Get Black Mesa: Source instead from www.blackmesasource.com.

This may be controversial, but I like Skyrim more. I still really like this game, especially Shivering Isles. Guilds' quests are more interesting here.

There's something of a schism between the CS games. In CS:S, recoil is less. Headshots are always 1-shot kill, and I have fun with it. Get it on sale.

Very fun game! Not like Sid Meier's other games, and doesn't have the greatest replayability, but it will suck you in, and you can replay occasionally.

Very fun game without mods, some mods might improve your experience. I highly recommend this game, it's addictive. Mods disable achievements. 6 out soon

Fun alone, great online, amazing with friends. You pretty much need Half-Life 2 for models and textures. Try mods like Wiremod or Prop Hunt for more fun

It's a simple dungeon crawler that gets more complex as you get into all the different items. Similar to dungeons from older Zelda games. Fun for cheap.
