This one of the hardest games I've ever played, and a fun homage to old-school platformers. The hand-drawn art is gorgeous, and the gameplay offers a smorgasbord of throwbacks that older gamers will recognize. Be prepared to swear in frustration working your way from checkpoint to checkpoint, and relish the accomplishments in defeating the more challenging sections.

This one of my favorite games - appears simple but is devilishly complex. You'll want to proceed through the entire tutorial, and then ease into multiplayer, expecting significant early failure. Stick with it though, and experience one of the finest in free to play competitive RTS.

This is a great strategic blend between Magic the Gathering, Monopoly, and basic Stock Market trading. Be forewarned - a modest game can take HOURS to complete; however, if you are into deep strategy and complex, long form gameplay you won't be disappointed.
