This is certainly a post I want to comment on. This is in no order. And I cannot list 10 games.

• Oni (this one is #1 for me)
• Mario Forever (the global fanmake community is something)
• N the ninja flash game (N v2.0, N+ and N++) (this game is something else)
• Megaman series (1,2,3,4,5,6)
• GTA SA and VC
• NFS series – Most Wanted, Carbon and Underground 1/2
• Dragon Ball Z Budokai Tenkaichi 3 (2 player combat does not get any better)
• Counter Strike Condition Zero/1.6
• House Of The Dead 1/2
• Metal Slug series (1,2,X,3,4,5,6,7)

A few extra mentions:

• Mario Forever Galaxy (if Galactica and Mario franchise made a perfect child)
• Genocide (too obscure, can DM full version personally)
• VVVVVV
• Duke Nukem Manhattan Project (the feels is pure rusty nostalgia)
• DAVE (DOS game, not the same as Dangerous Dave)
• Pocket Tanks Deluxe
• Marvel vs Street Fighter (on Arcade)

Linux is now just a shell, and GNU a bunch of Qt programs. Steam is the real deal.

I will interject for a moment to say that what you are referring to as GNU/Linux, is now GNU/Steam/Linux. Steam is an integral part of Linux that allows games and other non native applications to be ran natively without virtualisation.

If your suggestion is on the lines of a 4Chan thread style imageboard, then we already have the chat toggle when we use web browser for Lemmy. Not a bad idea, it does give Lemmy a different character altogether, and it can create opportunities for both reddit and 4Chan style users.

The chat toggle pretty much acts like this. However the issue is that there are also multiple posts, and what you are describing is a 4Chan style imageboard, but instead there is only one thread on the board. Kinda weird when you think of it becoming like a YouTube live chat, where the witty spammers and trolls are kings.

Downloading a user should be a helpful feature too.

Unrelated, but someone should also try a Lemmy comment archiver like one of those services for reddit.
