"You won't enjoy it for long"

"I played it for 30 hours"

Orange is hard to rhyme.

The game is fine. You CAN play to win to a certain extent. Basically to buy weapons/frames; that you can normally farm the parts for and make without spending a dollar. But if you want to be good, you gotta play the game because it's all about the mods you get(mods being weapon and frame enhances). I haven't spent a dollar and I got some seriously powerful stuff.

It can get repetitive or dull fast for some players.

Be prepare to farm a lot or pay some $$$. In game currency or credits can only buy a few things in the game sadly. You can't buy additional Warframe with credits. If you want more Warframes you will have farm or pay for them in platinum(cash shop currency).

Also I would suggest choosing Excalibur as your starting Warframe instead of Mag and Loki. Mag provides a better shield but most of her skills(excluding crush) aren't all that good. Loki is a stealth-type warframe. Sadly most random players go acting like they're Rambo and alerting the enemy. Soon as the enemy is alerted its pointless to do mission using stealth.
