Actually, this is something I specifically wanted to call out: 5E looks very friendly to house rules.
Because 5E is designed for modularity, and the Basic rules look like they pulled it off, I'm upbeat about my prospects for tweaking things.
Agreed. I think The Basic Rules will serve as a base platform for my game quite well. It seems to provide a good solid foundation to work with. Much like the reason I like Swords & Wizardry. Strong foundation to tweak as I see fit with house rules. Largely because I am in the camp that thinks it is easier to add rules to a game or systems to a game than to take them away.
