There are Monty Haul style games like that, mtfeeney. It is certainly a style of campaign that has been around for a long time, before Shadowrun even existed. However, that is essentially the same as playing in god mode. Whenever players can simply push the 'made of win' button, and be done, then it cheapens the game. Getting major gear, such as VTOL aircraft, should be the matter of a run or multiple runs, to either steal it, earn the cred to buy it, or to do something big enough that the plane is part of the payment. When players can, on a whim, pick up gear reaching hundreds of thousands of nuyen or more, then there is a problem, unless you're in a long-running campaign, where your players have risen to the level of people like Fastjack, Kane, or the other Jackpointers. In other words, you're street legends.
Part of this is a genre bias, of course. Someone who comes from the Fantasy genre, for instance, may expect to find a +2 sword when they go into that sixth-level dungeon as a matter of course. To them, killing everything that moves, taking their stuff, and selling what you can't use is second nature. Someone from the Superhero genre, where a playboy millionaire who dresses up in costume to fight crime at night isn't that uncommon, might not like the idea of being 'in the trenches', having to make choices about their lifestyle based on whether they want to save up for some new gear.
Cyberpunk, and by extension, Shadowrun, is not like that. The people who can get away with killing everyone and taking their stuff are few. The ones who can stay employed after gaining a reputation for wanton slaughter are even fewer. High rollers in the shadows are uncommon, to say the least. Why would someone who can just sit back and enjoy life without ever needing to actually 'work' engage in activity that is not only incredibly hazardous, but could risk their whole lifestyle if they're caught?
To put it another way, its like playing Super Mario Brothers (the original one), and having a star pop up every few seconds. Sure, it feels badass to get the star and go invincible until the power runs out. But that is because the star is rare, and so it makes you appreciate it more. If you were constantly in 'star mode', then the game would get old, real quick. Or perhaps you could compare it to the latest Tomb Raider game. By the end of the game, you have badass weapons, including a commando rifle with a silencer which you can use to make awesome finishers on your enemies. But the reason it feels so badass is because you earned it, traveling over the map without even a torch to start, gradually gaining new abilities and gear, and learning from countless deaths. Because you earned it, because you worked your ass off to get all those upgrades and skill points, it is special.
