Valhalla and Shadows are two of the best-selling Assassin's games even though they've been exactly equally as shit and tedious since Origin, so I'd put a [citation needed] on your "increasing irrelevancy".
Also which big game studios don't suck? The list you give below has, the top 10 largest in order,
- Sony (I guess defensible, idk),
- Tencent (lol), Microsoft (lmao)
- Nintendo (legal almost as predatory as Oracle)
- NetEase (???)
- EA, Epic, Take-Two (sincerely wishing prostate cancer to all three of those CEOs)
- MiHoYo (literally one gacha game), and
- ROBLOX CORPORATION.
My entire experience with Sony is that I loved Patapon on the PSP (I would sell my fucking soul to get it to play on a smartphone god) and I watch The Last of Us and that's it. None of their games exist as far as I'm concerned because I can't play them on PC. What, I'm going to play TLoU 2 without playing 1 or GoW 4 without playing 1-3? Go fuck yourselves.
