Every great game maker had to start somewhere - so why not school?The fourth annual Level Up Student Showcase was held in Toronto this past weekend, showcasing the work of nearly 100 student-run development teams. Everything you could imagine was on display, from well-established genres to completely unique offerings unlike anything we'd ever seen.There were plenty of great games to choose from, but there were five in particular that really screamed "the next big thing." Don't be surprised if you see these games - and their developers - making a big splash in the near future.
