You absolutely should not remove them. It depends on the job, and the complexity of the games you create, but worst case if the interviewer is personable (e.g. not your terrible interviewer) it's at least a talking point and can show you're more well rounded, but if the job deals with the same languages that you've programmed the games in it's even better. It's definitely a different part of the industry but I've never heard of games being detrimental to a portfolio, and in fact I've heard some respect/praise for ideas from game development a previous job (doing front end web development).
