The main thing is to introduce a limit on the characteristics, so that there aren't characters with a strength of 45 and everything else at 15, or introduce a link between stats, so that to increase strength to 30, you first need to increase endurance to 20, or all other stats, so that there isn't a large gap between them. You can also introduce racial restrictions, as is often the case in games.
Be strong. Believe
