That's a lot of new achievements. I especially like the color coded ones ^^Included in the first tag should be the last Monotype Tier achievement I missed, giving me Monotype Master, along with all of the Generational Tier achievements giving me Generational God. If all of these clear, I believe I have enough achievements for Hall of Fame (but I'm not sure). Let me know if I missed anything. I'm also going to leave some ideas for achievements in a second tag. Feel free to use as many as you want.
