Millenium is very nice game if you enjoy old schooll rpgs. There is lot to discover and option to turn on visible encounters so you can avoid most battles if you want. Grinding is not requred to complete the game even in hard mode so most of the gameplay is discovering new stuff.
Start of the game is little slow as you control only one character and money is very tight. Later on you will get new members. By then the game really starts to pick up. You can find some fantactical locations in dungeons, most music tracks are very good and banter between team members can be pretty funny.
There is lots of optional stuff like secred rooms and sidequests. The main quest is a bit short as this is only a first part of the series. I will propably get next one in the series once there is a sale. You can import your save file to the next game so there is incentive to find everything.
Very solid RPGmaker game 7/10.
