fully understood, i find i have big ideas a lot then find i have to tone-down my ideas to fit what i can actually archive (which is sometimes a little disappointing) however things sometimes workout for the best & taking the time you need is always a good idea this way your not working on just fumes and getting 'burned out', dis-hartened or annoyed with things (and its easier to find a workaround or fix).
will have to take a look at the pinball simulators as they sound pretty cool & if there anything like 'Pinball Wizard' then they will be epic!.
all the best, hope all is going well :)
