Both are very good games! Both are keeps for me.

My advice for you is to purchase the one you like more based on shoot layout. Looking at your collection you seems to like more flippers and loaded games (besides GB) so guessing radical is more your style.

From a purely price perspective the radical sounds like the better deal in general terms without knowing condition (which I would question why that person had not already sold locally based on price).

Good luck and lee is posted.

Honestly. But both. I don’t think you will regret it.

I honestly would not pass up either.
In ranking of sys11 games I both at top tier along w wwind and space station and earth shaker.

Right behind those is Rollergames

I can say 100% that radical is a great player! It is desired for the game. The price is because it is rarer than many sys11 AND good.

Truth be told, there are lots of rare games that suck and the price reflects it. Radical does not suck

If they were the exact same price and value, exact same condition, exact same ease of pick up... I would probably get Radical first by a slight hair.
That said... I still suggest both. They are a really good pairing of sys11 games for your collection.

curious OP... is there a reason you are not buying them both?

They are both on your wishlist, so seems odd not to jump.

Limited funds? Limited space? If so then consider selling GB as from the looks of it... after you buy 1 of these, you will be hunting the other if I predict accurately Once you get your first real classic... you will likely hunt out other early ss, late ss, and alphanemerics
