I don't remember, other than the TNG episode The Game, of any other types of video games in Star Trek.

Obviously, you can go into the holodeck, load up a simulation, and have fun, but consider the following:

• A holodeck might not be available to everyone, especially people outside of Starfleet. It's possible you can go to a service much like Quarks, and book sometime on a holodeck.
• As a number of episodes demonstrate, a holodeck isn't perfect.
• If you're like me, you like vintage technology, so a PC, console, and controller (which by that time would be really vintage) is perfect.

Are their any references to video game companies or hardware still being around?

This might just be speculation, but given what we've seen some of these engineers do, building your own console to run a game but be trivial by that time, so you may not have any companies that produce that type of hardware anymore.
