I would love to take an Interrail, eg to visit France, but it's x days in one month (8 days is 292€ per person) and doesn't match my travel habits. I would prefer to make short travels everyday rather than long travels 8 days of the month.
Edit: global passes let you travel everyday of your pass, with passes of up to 3 months: https://www.interrail.com/en/interrail-passes/global-pass
