I'm rather fond of the old Jigsaw activity. It can be made practically into a game, and also promotes paraphrasing, note-taking and group research techniques. Basically, split the class into groups of about 4. Give each member a different piece to read and some objective ("retell it", "pull 5 important points out of the text", or the more competitive "pull out as many important points as you can remember"). Then, in pairs A-B, and C-D, the students share what they know. Then A-D and B-C again share, this time sharing both what they read, and what their original partner told them. Idea is that the students all learn something, whilst also communicating with a set goal.
Roleplays and group presentations also require no computers.
