Xenonauts is a good example, very much like XCOM games, but once the game is over, it's 2 or 3 images and bam, done.
Back in the day, games used to last forever (we talking all genres of games) and the endings made the games worth it... like giving closure (almost like relationships)
Now, the story is BS and the endings are just as bad.
That's why it's hard for me to find games that 'grab' me... I buy games all the time but nothing keeps me going for longer than 5 minutes anymore except maybe Diablo 3 and Battlefield 4/3
Everything else... *spit*
I've actually decided to basically stop buying games now - simply because I can spend R300 on a game, get it, play it 5 minutes and never play it again.
I have like what, 150 games on Steam, I only have 3 installed now and that's the Trackmania 2 games.
It's sad, honestly.
