It’s well worth the experience. Montreal has one of the biggest game development communities (at least in North America). In the 3 month program you have access to monthly playtest in the office space (both public and people in the game dev community). To elaborate, Execution Labs is partnered with ‘GameplaySpace’ (http://gameplayspace.com/about/) - an open office space shared with other developers… You’re always in contact with other indie and AAA developers to get instant feedback on your game. Ubisoft is out there as well, and we even had a fieldtrip there to visit the ‘RainbowSix Division’ studio office. It was pretty epic! (lol, no pun intended :p). After visiting the RainbowSix Division studio, we strolled to another Ubisoft office where each team part of the cohort had a chance to pitch their game to various producers and high level people from Ubisoft.
That’s just a small fraction of the experience going there for 3 months…so yes, it’s well worth the time and effort to try! 
It’s defiantly an advantage if you want to succeed in this industry. I’m not trying to sound like an evangelist, just telling it like it is. To be fair though, you benefit from it in the long run. Just trying to help indies out there with potential get a chance to succeed…and feed their family! haha. #indiesunite
