Flash Gordon is a keeper,solar fire will get old.

I have a Flash Gordon but have never seen a Solar Fire (very rare in Australia too) Had a look at the game play on youtube before, looks pretty fun. For me though, I would prefer Flash Gordon (even without ever playing a Solar Fire) essentially due to having speech. Speech on FG is great & key part of the game, also features like the two way saucer, strobe light & single drop target are interesting & nice features too.

FG is a keeper game for me, I tend to agree with what Grizlyrig said about SF getting old, it kind of feels like it would to me too for some reason (which I can't define).

My vote is for Flash Gordon.

Another vote for Flash Gordon, "Emporer Ming awaits"

Not even a close contest. If you can master Flash Gordon, you are an exceptional pinball player. Great game.

FG is a great game no doubt but I'm going to say SF instead.

With SF you get
2ball or 3 ball MB
3 magnets
Lots of hurry ups
Plus it's not too tough to find a FG while SF is a harder to find.

I think you'll be happy either way. Get the one that is in best condition?
Sell your personal belongings and get both?
