So you've looked through this catalog and found a god you like, what next? If you're a player, talk to your DM about how to best incorporate a god into a campaign. If you're a DM, consider how your players may interact with the gods you are including. Are they distant and aloof? Or do they frequently interact with the party?
For spaces to play with a party or find resources, check out The Source Comic and Games, Fantasy Flights Game Center, or The Gaming Goat in Minnesota. If you are outside of Minnesota, check online for local game centers. I have had some pretty good luck with using Roll20 and Discord for playing online, but check out message boards, like the D&D subreddit, for what other players are using. If you're looking for a group to play with and feel comfortable chatting with people online, check out the Looking for Group subreddit. For online resources, check out DnDBeyond and the Forgotten Realms wiki.
Are you interested in learning more about D&D but not playing yourself? Podcast/YouTube campaigns I recommend include Critical Role, Dimension 20's various campaigns (free episodes are on the YouTube channel), Not Another D&D Podcast, and The Adventure Zone.
This is by no means a comprehensive list, I am but a simple D&D player, and I do not know everything.
Feel free to leave me a message on the homepage if you have any questions, comments, or concerns, and I'll try my best to help you out!
