[citation][nom]Pherule[/nom]It's tempting to get TL2, but I somehow don't think it'll be as good as Path of Exile. I tried TL1 and couldn't get into it at all. Some people are saying TL1 > TL2, so I think I'll pass.[/citation]
In my opinion, TL2 was an improvement over TL1, but I loved both games. My main problem with 1 was that the end was so anti-climactic that I honestly didn't know I'd done it until I'd gone a number of levels through the post-game grind afterwards. (But, hey, that's me being an idiot.)
I thought the second one expanded on the silly fun of the first one and fleshed out the weak points.
However, if you didn't really get into the first one, chances are that you wouldn't get into the sequel either - they're not that different
