I do but sometimes my skin is all messed up cause your skin won't transfer over to that version so I'm stuck with a weird messed up thing in like tekkit classic and such. but vanillas fine i get this great nostalgia from it!
Alpha is a version where you can just chill out,the game was pretty simple back then there we're almost no mobs back then you could calmly pass through caves cause there was no danger of the creeper blowing behind you.
I do sometimes go back to the alpha and remember when Notch was in charge but time flees soon going to high school and losing all of my friends
but anyways back to topic,Alpha and beta but more alpha are the calmer versions.The first official released version of minecraft had grass and cobble stone to build with and yet to now it had exploded.Beta well here the game really get's it's challenge and mobs we're added mainly the hostile ones then after Beta came the bigger updates for Nether and the nether creatures new blocks and much more.
I mainly now play the latest versions of MC but I sometimes get back to the past.
