I'm fond of most forms of new game plus however I don't want the enemies to become more difficult. I don't hunt down every little bit of experience and wealth I can get for the game to become more difficult. Building my character into a power house is part of the enjoyment for me. I really enjoyed it on Parasite Eve when I had Aya so over developed that enemies took damage simply from being in her presence.
Those who talk about the enemies becoming more difficult seem more interested in a nightmare mode then a new game plus.
Now as for anyone who's about to claim I'm looking for an easy mode. Only if easy mode let you build and customize your own top end gear, gave you access to all spells and abilities, more then enough wealth to do whatever you wanted and required some effort to unlock.
It's sort of like setting down for a pin and paper session for me. I don't want the game master to look at me and say, "Here is 100 bonus experience points build yourself a monster of a character." Well unless the other players are getting the same treatment. However, I most assuredly want to keep hold of my mehket researcher Vanessa who's survived several major campaigns and developed into quite a power house. She's my character and I've lovingly built her into quite a beast.
Of course even if they don't put in a NG+ feature I hope I can build something of one for myself due to the respawning enemies. In Kingdom's of Amauler for example I walked around being careful not to complete any actual quest in the game. I just gathered materials to build my armor, purchased skill points and leveled my character up. It took a few days if I remember correctly. I then held onto that save in case I wanted to play through the game again. I did the same to Skyrim and similar to Jade Empire. As well as many other games. When I was younger I'd typically spend 12 hours the first time I hit the world map just level grinding. These days I can go longer though the maximum has been 128 hours in Star Ocean's case. With a true new game plus feature though I can do this while enjoying the storyline.
