I didn't say alike in all ways, there's definitely quite a bit of differences. But basically, both start off super inexperienced, and both can become very corrupted (albeit in different ways) by others who come along in the story... a bit too easily if you ask me, but this is a porn game, so yeah, lol! And both can also have pure routes where you basically refuse to get corrupted at every turn (either one or both of them). Just like how Vanessa pretty much is a big influence on Ben's corruption I'd argue if you follow her.
But as for Ben being a lazy shit, I mostly agree. Lol! Although, his situation isn't quite unrealistic... well... how it starts out, not how it progresses. Being a lonely gamer, sometimes the opportunities just aren't there, relationships, jobs, whatever, and believe me, you can try your ass off and still be stuck using that as an escape. There's a fair bit who are like that for more reasons than simply "being lazy"... sadly speaking from experience there. But... Ben kind of shows he is capable, just too lazy to try unless opportunities are basically handed to him. And I know no one who gets the opportunities Ben gets as easily as he does once the game begins.
Like I said, a porn game for you. Lol!
