I'd not use the word "realistic" in an entirely made up situation
fair point as is the rest of that paragraph. But. Some games are more realistic than others, not just in graphics or background setting, in gameplay and timeframes and how things interact and whether suspension of disbelief or immersion is the better option to enjoy the gameplay. Where these clash there will always be issues and where different players want different things there will always be clashes, but if the game is one way then join the game rather than fighting it.
Don't confuse modus operandi with intent. I get my fun out of planning, preparing, getting informed and following through on that. Your statement holds true for the way you enjoy your game, but in the end gameplay perceived differently by every single player in their own way. You can't just look at it from your own perspective and then apply that to someone else's experiences. Shouldn't be needed to explain, but I'll do it for the sake of clarity nonetheless.
Arguably its my perspective or arguably its the way the game is intended or designed to be played or enjoyed. Doesnt mean there arent shortcuts but cant blame the game for trying to stick to the original plan and not encouraging the shortcuts.
Your OP had strong implications that you 'had to' get to 10bn before the game could start for you, its not that way at all, thats your choice and fair enough. It also implied that this impression had been given by 3yo YT vids that this was 'the way', its not that either.
The forum is not against you....mostly Its now much clearer what you were actually asking. I still think you'll miss out on vast amounts of gameplay but it is your game to play as you want, we'll always agree on that.
