A couple or three decades ago, when lots of people on Pprune took their aptitude tests, there were no computer games (apart from that really anoying 'squash' game) and we still all passed. To be fair, even the most modern flight simulators, which after all, are only computer games, aren't that realistic, so I would think that if you have the aptitude, you'll pass the test.....don't worry, relax!!!
