Gosh anon, I’m sorry, and I’d be lying if i said I didn’t know that exact feeling actually it’s happened to me too- I think we just have to accept that every person has different feelings and we all approach a game with an entirely different set of expectations/perspectives.
That one person didn’t enjoy it doesn’t mean the game is bad! It just means it didn’t gel with their requirements for enjoyment. Sometimes it can come down to personal taste or even what has happened to the person recently- they may even come back to it and play it years later and find it’s something they actually do like, it was just the wrong time for them to play it.
Anyway, chin up, you wanted to bring them joy, and while it might sting that your effort was rebuked you had the courage to try, and that’s wonderful! Trying to make someone happy by introducing them to something you love is a fantastically brave thing! Keep the love of that game in your heart because it’s something that you had a great time with, and I reckon that the people who made that game would be super proud of you for having made the effort to promote it if they knew. The fact that you’re hurting just proves how much both the game and your friend mean to you! How amazing is that?! I think they’re both very lucky to have such a loving person there to appreciate them.
