The Tomb Raider reboot series tends to lag a little whenever Lara is left to her own devices in open areas, but if you press on and focus on the storyline, it'll be better. The action is good, the graphics and snowy-mountain-climbing are seriously GREAT, and the plot has lots of potential (unfortunately, the potential isn't quite lived up to in the next one, Shadow of the Tomb Raider). The fights with Trinity are awesome, and I personally enjoy listening in on the enemy's conversations before stealth kills. They're honestly quite well-written, and surprisingly detailed!
Tech tip/ spoiler alert: When you have to fight the bear, just run in and shoot it with a poison arrow and then run back outside to a safe enough distance so that it won't chase you. Do that about three times, and it should be dead. WAY less stressful than a full-on-bear-fight.
Also, I know it's antifeminist, but I would actually love to see Lara having a romance. Poor Jonah is so, so friend-zoned.
