Joanie, GameZebo is a website that provides reviews and they have some walkthroughs, although not as much as they used to. They are not a game website like BigFish is, they only link to other download websites. The difference between GameBoomers and GameZebo is we do not provide links to download portals that add tracking devices to your computer when you download their games.
Visiting GameZebo also adds a web beacon to your computer that tracks your browsing behavior. I have to block these trackers before I visit the sites. Prior to them adding all these features we did quite frequently link to them for walkthroughs but I no longer do that. Purchasing a game through one of their links will direct you to various websites to download from that you do not know if they are safe or not. We have threads here on reports of spam and pop-ups appearing after downloading from some of the links.
GameBoomers links to BigFish games because they do not use web beacons on their website and their downloads are all hosted on their portal so you know what you are getting is safe. They also have great customer service.
It is your decision on what websites to use, but we do our best here to filter our links so that you can do safe browsing.
