I think it's a stupid excuse. Especially since he's been bashing other games
What the fuck has that gotta do with anything?
It gives you a glimps into the real reason for his mission. You've wronged him once, probably by bashing a game he loves (Oblivion?, Gothic 4: Arcania?) thus making a mortal enemy.
Now he will post his one-liner variant of *lol, varporware* in every thread you show up. But since the varporware topic isn't so cool as of late, with the whole demo thing being released soon, he decided to focus on other things instead, like the time it took to develope AoD or your atrocious design decisions. Wait what, AoD has a bodycount score and NPCs will *magically* know it?!
Preposterous! I mean you took, like, years to develope the game in your sparetime and that's what you come up with? Omniscient NPCs? Years? Especially considering you've been bashing other games.
