Of course it's a waste of time, like all computer games are. It CAN be fun though.
On topic again: I actually find that map great! And I'm not joking! Of course, it's not a scenario (because it lasts 5 minutes and isn't difficult at all, I mean, it's not really 'playable'), but it's an excellent start; you understood more than the basics of the triggers and delivered a better work than many so-called 'advanced' designers. Just three things to improve:
-In your very first trigger ("run immediately"), make a camera cut towards the black space outside of the map (unlock the camera first). That'll disable the short 'jump' from a normal map view to the actual cinematic. After the cinematic, make a shot back into the gameplay perspective. It's disgusting to play with a different angle IMO...
-Add a Spotlight with a picture and hints in the objectives gadget!
-Make your cinematic skippable:
BTW, I noticed you used QVs to activate/enable triggers. Simply use the effect "Fire Event", that's much easier and faster.
Apart from that, great work! Good cinematic, eyecandy, RPG system etc.! It just is too short to be considered as a scenario. Extend this work to a real scenario and you ought to get a 4.2+ rating! Very good!
