Yes, keep in mind that it only takes less than a dozen large games to fill up a 64GB ATV.
If you like things like Aerial Screen Savers, a larger size could also help. I pretty much only see one of them because there is hardly ever enough space on my ATV to download multiple ones.
Another thing to keep in mind is that even on large games, there are still sometimes assets, that need to be downloaded to play a game or certain parts of a game. I have ran into the annoying situation where I was playing a game, but was unable to continue because I didn't have enough room on my ATV for additional assets.
Sure:
The Oceanhorn series:
Three games total, all require a controller. The first one, Monster of Uncharted Seas is like TLOZ, A link to the Past and Windwaker.

Simple, but beautiful, relaxing, but addicting. It is a great game to unwind from work, nice music and visuals.

Real Racing 3:
This one is free. I have spent a lot of time on this one. It is fun, although overtime, it turns into a pay to win game. The cloud saving is glitchy as well. I had a bunch of time invested, and stopped playing for like 6 months. Went to play again, and all my progress was gone. Still, it is a great racing game.
Plays okay with the first Siri Remote, but I prefer playing it with a controller.

Asphalt 8:
I haven't played it in a while as I prefer RR3, but it is a fun and fast pace racing game.
The "+" version is free on Apple Arcade. I bought (or downloaded, can't remember if it was free or not) this one way before it was on the Apple Arcade.
Plays okay with the first Siri Remote, but I prefer playing it with a controller.

Sonic the Hedgehog:
Classic Sonic. It is a great port. The App Store says that it is free now, but I thought I paid for it a while ago. I think it might be free with adds now, but you can purchase the ad-free version via IAP.
Plays okay with the first Siri Remote, but I prefer playing it with a controller.

Fantasian:
If you like RPGs like FF, then Fantasian might be for you. The creator was one of the same creators of the original FF game. It looks amazing, and gameplay is nice. One of the best looking games on tvOS.

A remake from the SongPop game that was also on tvOS. Great game to play with the family, especially if you like all kinds of Music. It is like "Name that Tune". Basically, you listen to music, and compete against others to guess a song name, or artist name, as fast as you can.

I can give you more if you like.
I have a lot of games that are no longer available to purchase as well, such as the DuckTales Remastered version. A lot of the games that I purchased are no longer updated, or were pulled from the tvOS store as well.
One of my favorite games of all time is the RISK game that is still on iPadOS and MacOS, but was pulled from the tvOS App Store last summer.
Gaming developers are leaving the tvOS platform like crazy. Hopefully Apple does something to turn it around.
