I got tired of accidentally browsing games from publishers with a track record of shutting down always-online titles and making them unplayable. So I built a simple tool:

SKG Publisher Warning

It’s a userscript that checks the publisher on every Steam/GOG game page against the Stop Killing Games Dead Game List. If there’s a match, you get a small amber banner with the reason and a link to evidence.

What it flags (16 publishers): Ubisoft, EA, Microsoft (Activision/Blizzard), Warner Bros, Bandai Namco, Sony, Square Enix, 2K, NCSoft, SEGA, Capcom, Rovio, Gameloft, NetEase, Nexon, Atari

Why it exists:

• Anthem (EA) — killed Jan 2026, always-online, unplayable
• Warzone Mobile (Activision) — killed Apr 2026 after 50M pre-registrations
• Concord (Sony) — killed after 2 weeks
• The Crew (Ubisoft) — the game that started the SKG movement

The banner:

• Amber/orange, matches Steam’s native DRM warning style
• Dismissible, does not block purchases
• Links to per-publisher explainer docs with sources
• No telemetry, no tracking, open source
