Thing is, when he's not in his porch, this old guy's day job is getting Freemasons to invest in Cuba. Or something. I suck at analogies.
Long and the short of it, Pachter's job is getting people to buy into companies, and that includes investing into videogame companies. He actively works in this industry, and advises people on what shares to buy in what company. If he can't be bothered to do a little background reading, that doesn't just make him seem ill informed when he's spouting off, it makes you wonder just what he's telling people investing in videogame companies.
