New to C#, Memory Reading/Writing

[SimpleF]

Hey guys

recently started with C# and memory reading, thanks to you guys, i had no idea where to start with making a bot and just looking thru some of the topics here made it a bit clear, and memory reading is amazing,

however im wondering about memory writing ?, if you do that on an MMORPG game, wont the game detect it ?
and why would you want to write to memory ?
what would you have to think of if you ever tried writing to memory ?,
im pretty sure there has to be something you have to think of before attempting to do something like this, it cant be just as simple as writing to it and hopeing that the game wont detect it.

Cheers
