I used to play D&D back in the day. I started with Basic D&D (the Red Box) and played up to 2E. Then life got in the way and then I didn't play for a long time. I just got back into it (2016) and am really enjoying playing 5E. I think I'm a pretty good DM and of course enjoy the opportunity to play on the other side of the table as well.
Recently been nostalgic for old school D&D, and got tired of the "Super Hero" nature of most 5e characters, so tried out Dungeon Crawl Classics and then Shadowdark.
Currently, Shadowdark is my preferred system.
