Can someone help me out? I stuck in some really boring ones like
bishoujo games, G-Collections, Himeya,
Hobibox, Peach
Princess, Jast USA, MIXX, Otaku Publishing, SNK, Neo Geo Pocket Color,
reviews, ecchi, Viper, Super Real Mahjong, X-change, ZyX, Sogna, pretty girls
Need more ideas.
I hate to say this, but what about some of these:
H-games (with or without the hyphen)
Hentai games
adult games
anime
anime games
doujinshi
life-sims (with or without the hyphen)
love-sims (with or without the hyphen)
I will say that if you use “H-Games” and “Hentai Games” as meta tags, include somewhere in your site that those terms are offensive, and incorrect.

Oh, some other ones too:
Himeya Soft
CsWare
Crowd
Angel Smile
training sims
etchi (different spelling for “ecchi”)
add oppai too 
Thanks for the suggestions. I’m wondering whether to put ‘MILF’ in since it seems like the latest fad in the porn reality websites. But I joke. How do I get my website to turn up in searches? I type in ‘bishoujo games’ and my website seems not be among those listed. What gives? Do I have to submit my website to something?
I think you have to wait for a little bit before the engine caches your site. I know I have to wait about a week before the engines pick up my new site layout. Until then, They will show my old layout.
I see I see. Thanks 
A good way to get your site in search engines is adding your url to http://www.dmoz.org/
When you add your url there, your site should be listed with many search engines. Including google, lycos and hotbot.
