absolutely not
i even hated lending things to my ex because he would deny case damage that wasn't there before he got them
and i always watched him break up weed on the nearest game case to him and it made me cringe ugh
i had to rebuy harvest moon back to nature because my aunt borrowed it, and my brother borrowed my genesis and a couple games, and i'll never get them back now that i've been booted out of the fambam.
i'm too flighty and things happen in my life too much for me to be friendly about letting people borrow games. i almost lost a number of them to my ex too, but i recovered them, fortunately.
it really bothers me to let people borrow my stuff. even my ps2 controller has a giant knife slash on the bottom of it from some mishap via my ex.
so yeah, no, i'll never lend a game again.
and anyway, i'm not a rental service. when i lived with a roommate, i let him play some games, but i handled them, and he only got ps3 discs from me... i refused to let the case leave. before i moved i made sure all the games were in their cases, too. ps3 games are pretty hard to scratch, so that was whatever, and he normally only wanted to play AAA titles or games not worth a lot anyway, so it was whatever. my ex, i kinda converted him to a niche gamer/semi-collector, but he was still just not gentle with cases and it pissed me off. but it meant he wanted to play my niche games a lot, and ughhh.
between my ex using my collection like a library service, and my ex-roommate using my room like a giant free best buy (at one point he had 3 of my USB cables and my ps3 power cable
) i'm now just closed for a service i was never open for in the first place.
