Yes, as it states DRM-Free and I can't find update outside Steam version. Also Dreamcast Collection is sold and DRM Starforce is mentioned, not steam.
Then there's still the physical version. I can't be 100% sure for digital download ones (and even many local retailers are selling it trough their own bloatware) as those services could get updated version of the game, but with physical I can be almost certain as it would require seperate patch downloading and I'm almost certain they didn't come with Steam keys (kinda confirm as I can see those being sold second hand on ebay and one regional similar site).
Steam version actually had bug with config utility as physical versions installer would add single registry value that steam version didn't do and nobody were able to save config changes.
Yes, this is really silly situation. Personally would've liked to just update the article to match steam version as sega has been trying to guide people to steam and forget other versions exsisting. But as the situation is, there will be 2-4 articles per game of that collection...
