I started off reading lots of shoujo manga as a kid (from nakayoshi, hanato yume and asuka comics.). I think when I was in high school (年ばれちゃうかな?)I started off playing Angelique series after I played Tokimeki Memorial. In Japan (back then...っていつ?), Tokimeki Memorial popularized renai simulation...
I think as long as its not a visual novel type game, it should be easy. Like adventure, simulation style otome games from like Nintendo. Its not a otome, but something similar to Tokimeki Memorial type games would be easy to play and understand Jp.
