Free games reminds me of childhood

Playing free games in the internet never interested me much at first as I thought this was for kids. Little do I know that in time, I would also be addicted to those multiplayer games especially those MMORPGs (massive multiplayer online role paying games). However, when I do get tired o playing those stuff once in a while, I somehow resort to looking for those classic games that I have always enjoyed which sad to say are hard to find as they have been out a long time now. Many games like my favorite shooting games
wolfenstein, and so many more games that have played a part in my growing years still has appeal to me everytime I see them. Once I start playing them somehow I cannot stop until I finish them again and I cannot even sleep until I finished at least a stage or leveled up. I cannot imagine myself regressing back into childhood but I always loved playing games back then and up until now, I guess that habit is still there and there is no use in denying the child in me who wants to play these things.
