As a DT pinball table user, there are exclusive things that only the Future Pinball Program has achieved, like being able to hit tab key and see backglass. Also you can change points of view by simply pressing the F1-F7 keys. The Physics really don't compare to Visual Pinball in my opinion, as some shots are simply not possible using the physics in Future Pinball.
Future Pinball also has the integrated video which VP has not achieved yet.
There are many reasons to have both, Future and VP installed, as each program is unique in what it can do.
(Cabinet users may have different experience, but I don't know, because I am not a cabinet user. YET!!)
Really the only downside to Future Pinball is the physics, but as stated in the above post, they have progressed a long way from where they started. BAM physics just being an example of how they have tried to improve the overall physics of Future Pinball. I am sure if they have Devs like this VP community has, they will keep striving to have the perfect physics and overall better gameplay. I am sure alot of people have put in alot of hours into trying to make this better for everyone else, and it is appreciated.
I am not going to get rid of my Atari 2600 Video Pinball because Super Nintendo comes out with a better pinball game with better physics. Yes the physics are not really great, but I will keep playing it and enjoying it every chance I get.
Just because something is better or newer, doesn't mean you kick everything else to the curb. Future Pinball deserves to have its place on the Virtual Pinball Totem Pole.
That goes for older VP tables too.
Yes VPX blows away VP8 and VP9 with all its new capabilities and physics, but I am not going to get rid of all my VP8 tables. I actually enjoy each and every table made. Even the older VP8 tables at IR Pinball are all worth having in ones collection in my opinion. It is actually amazing what they accomplished back then with the capabilities of the VP program. (You could only use jpegs and nothing over a certain resolution. So this meant no transparent png pics. AMAZING!!!)
In short,
I would encourage you to try out Future Pinball for yourself, and see it in action before making a decision on whether you want to kick it to the curb or not.
Same goes for all the old VP8 tables. They are all worth downloading in my opinion.
Have a great weekend!!
