Difficult choice between DMC and Tomb Raider but I'll go with Tomb Raider. You could do some really cool stuff in DMC though.
Had the same dilemma and came to the same conclusion. I really enjoyed both games, thought they were fantastic reboots, but Tomb Raider just had more meat on those bones. I'd go as far as to say Tomb Raider is probably my Top 3 for this year.
The Tomb Raider reboot was the first Tomb Raider game I've actually enjoyed thoroughly enough to finish. As far as a reboot goes, that's about as good as they could do... To be fair though, I haven't played enough of the other games to form any sort of opinion about them at all ...
I wish Tomb Raider was longer and more open. It was fine as a straight shot shooter with some stealth and traversal elements, but I feel its combat, which was actually quite fantastic, was wasted by its linearity. It doesn't have to be the Far Cry 3-type of open, but more open area encounters like that one ambush part would've made it alot more memorable. Very much looking forward to the next one. I really do hope there is a next one!
