The last day of November 2007.
But like theshim's saying, how long you've been playing doesn't really matter. Some people are better at these games, plain and simple.
That and the fact that there is a difference between how people play the games. There are those that constantly pushes themselves forwards and always strive to get better and as soon as they beat Normal mode never touches it again and move on to Hard, then Lunatic. Then there are those, like me, who wasted a crapload of time messing around on Easy mode. Then slowly, very slowly, moving on to Normal mode and hanging out there forever. Its actually not that long time ago i started playing on Hard and i still have a tendency to waste some time on the lower difficulties. Its probably because i have some weird tendency to not seek higher difficulties but have an idea that i am not ready even though i know i will never improve like that.
A final thing. There can be a big difference between how much time one spends on the games. You can play them an hour once in a while or you can spend your time on NOTHING ELSE WHATSOEVER!
But there really is no reason to be jealous. Everyone should just take their time and make sure to have fun along the way, then everything will be fine.
As a direct response to the topic: So the cheater wants to know how people started out huh? Thats alright then. Someone showed me a crapload of Touhou videos, both of us completely oblivious (damn, i hope that word means what i want it to mean) about Touhou and we were amazed by the players skills. In time however i realized: Why don't we try this out ourself? I hunted down IN as that was the only games title i could remember and i started playing. To begin with i wasn't very addicted so the first couple of months went slow. I estimate it took me 4 months to beat IN Extra. Another one to beat PCB Extra and several before i beat MoF extra. Silly no? I'm simply not a very patient dude when it comes to restarting games when i fail. Take EoSD extra for example. I haven't beat it and thats mainly because i don't feel like restarting when i fail. So thats why i'm the slug around here! A very obsessed slug, mind you.
