"モデルDEファイト(Model DE Fight)" (moderu DE faito) is a simple arcade fighter/versus tech demo with some mildly animated anime girls, and uh, that's about it. I'm not sure what the "DE" stands for, so here's a wrong answer: "Don't Even". This isn't worth it.

There's no English translation for the game, but that's okay. The language of bad games is universal.

The graphics in this game are passable, but could be better. And while it's vital for any game to have impressive visuals (gaming is a visual medium, after all), there's more to a game than just the graphics. To be worth a gamers time, the game must match top tier visuals with top tier gameplay, and that's not happening here.

In fact part of the reason the assets look okay is because the character designs are stolen from commercial properties... yep, this game is infringing a number of copyrights and will likely be removed.

It's also more or less an asset flip, being just a matter of filling out someone else's fighter/versus template with stolen characters. This kind of thing is not okay, even if the "developer" isn't directly trying to profit from it.

Plagiarism is not okay.

Even though this is "free", it failed to appeal to the 120 million+ gamers on Steam. SteamDB showed the game peaked at only 7 concurrent players... this is a dismal public reception. This was so bad they couldn't even give it away.

Bearing in mind that free games don't add +1 to your game collector count, should you bother adding this to your library and downloading it?

Not this time. This isn't worth downloading. While this won't cost you any money, you get what you pay for, and sometimes, even when the game is free, it's still not enough.
