I am looking for a laptop or a 2 in 1 laptop that can play minecraft and undertale my budget is $450 and I hope you can find or know about one. I would like it to run relatively fast but if you can't find one like that it's fine
You should have too much of problem finding a laptop that can do what your requesting but probably nothing higher than 768p and you will probably have to add addional memory over the base.
May want to look at HP/Dell/Lenovo systems or even going the used route.
