I am generally shocked how much worse this one is compared to the 2600 version, like it even looks worse in terms of visuals. Yes it doesn't include aspects from the arcade machine where there are ships that shoot out missiles. Compared to the 2600 version that has these many ships that just crash into the bases. But I cannot believe that they legit just made the entire game of flat landscape compared to before where it seemed like the bases were in trenches, which is mostly the style at which the arcade had it, that even the 2600 emulated it. But here this is just a flat landscape and it makes it so that you have less time to actually save a base if it's about to get hit. Not only that but it just is a worse version of the arcade machine that isn't even fun.
If I have to put a ranking in terms of the 3 versions that I've played it would be:

1. 2600
2. Arcade
3. 5200
What a massive letdown, and while it is more like the arcade version, it just feels like a worse version of the 2600 version, while looking worse.
The most insulting thing is that they remove the blinking light from the incoming missiles that are about to try to hit you, and they just made them straight colored lines and wow that is a nitpick, it indicated whether or not they were going to split or not. The blinking lights were purposely put there because in case there was a missile variation that split, you could see it. In the 5200 version it can't see it, and it's small detail that got removed that makes it worse than the 2600 version.
