I only watched about half of it, but I would wager the turn-based nature wouldn't sit well with Halo, unless done right and not as slow as the video portrays. Also, spells, items like Phoenix Down, and stuff with obvious equivalence of most other RPGs would have no place in it. It's a neat concept, but it'd be tricky to pull off right. It'd probably have a RPG/shooter hybrid, not a pure RPG. Having it too much like Final Fantasy would be a bad idea. The storyline would, obviously, need to be ala to the shooter games of Halo. Still, it was pretty interesting to watch, though the players look funny completely frozen when not taking action (I know that'd be fixed if such a game existed).
Wtf lol seen this video about 3 hours ago and wondered whether to link it but thought it was to boring but its good to see that if i happen to miss something on the internet theres a good chance il see it on these forums
