Ok, I have reviewed the footage and reconsidered my earlier comments.
Firstly, I am not knocking the Intellivision as a system. At the time of release it was better than many from my memory. The video is a little frustrating for me as the player did try flying fast at all which, makes it dangerous but exciting. The Intellivision version for me seemed a little lack-lustre in terms of GFX and sounds and not representative of how good the system is. I take back the word 'awful' because clearly, I can only judge on what I see and hear in the video. Still, I do think it could have been better and the only real way to objectify the game on all these machines is to play them all. I suspect only a few people have that privilege.
I also made the statement that I am a big fan of the A8 machines yet the original 2600 version felt like more fun to me and seeing these versions on video made me question does a better machine make for a better gaming experience. Hell no, hence we are all here.
So, as I say, a poor choice of wording on my part but I stand by my gut feeling that the 2600 version is best for the reasons I gave and not because I am a big fan of that system.
