Yeah...It's true, for example Final Fantasy did not have a feature to see the monster lvl and see if you can match it but that system is nicely hidden away and it was revealed the monster stats and lvl through the use of scan magic and all that information was stored away in a bestiary.

If you see the level of the monster it just makes the game even easier to go past the area by just grinding and leveling up your characters. I think without having the monster lvl being shown it just makes the game much more harder and rewarding when you managed to have monster stats filled out used through perception.

I think in Ultima 7 that they don't even show you the lvls of the monsters within the game until you beat it or have some kinda spell or item that shows the monsters stats...

Boy its been a long time since I played it..
