Currently there are 5 games on discount in XBLA. Of course the one I want the most, Zeno Clash, is exclusive to Gold members but whatevs. My time will come for Zeno Clash. Here are the games: 
 
- Lara Croft and the Guardian of Light 
- TMNT: TiT Re-Shelled 
- Hard Corps Uprising 
- Comic Jumper 
- X-Men Arcade 
 
Which of these are worth it? I don't play multiplayer. Also, I see that next week Torchlight will be 800 points. I hear Comic Jumper is very hard but I really like a challenge. Is it Demon's Souls hard or is it just frustrating?
 
I have 2000 points, and all these games are half off.

  @xyzygy: 

 
Where's the answer for 'none of the above'?
 
Maybe the Lara Croft game if you have a friend who wants to play co-op.  Maybe Comic Jumper if you don't mind sort of boring gameplay.  Yeah...other then that, pass on those and save your money.

I remember Lara Croft being surprisingly good. I own X-Men Arcade solely because I have a lot of memories of playing it with friends when I was younger. I wouldn't recommend buying it if you haven't played it before.

Comic Jumper isn't particularly hard, it has some difficult moments for the wrong reasons, but I enjoyed it quite a bit. It's definitely a game that suffers from stretched out levels. I'd recommend it over the others, since its the only one I've personally bought. 
 
I do want to play Hard Corps Uprising, since I love me some Contra.

What JasonR86 said, none are really too special, but I think Comic Jumper is the best on that list.

This would have been far better as a poll, 
but I'd say Comic Jumper out of those, 
But honestly even that's not good for much beyond a few good one liners

TMNT is getting pulled soon.

Comic Jumper is funny, but lack good gameplay, which is what makes it hard.

Lara Croft is OK.

X-Men is kind of awful. It was meant to eat quarters in the arcade, and having unlimited continues kills the fun.

I never played Uprising. I would imagine it's damn hard.

I would say Lara Croft for sure and wait for Torchlight. Torchlight is at least 30 hours of to S-Rank.

Lara Croft and Comic Jumper.

X-Men Bitches

I liked Lara Croft quite a bit.... I found Comic Jumper...fun...enough...
 
Get LC... I S-Ranked it without reservation... I also S-Ranked Comic Jumper, but... it was... fine....
 
Do you like "fine"?
 
Wait.
 
LC=4 stars. Maybe 4.5... Okay, wait... I played Co-Op thru the whole thing with my wife... extra half star right there... So, yeah, 4 trending on a 5.
 
CJ=3... okay, 3.5 stars.,,, right, it's much fun and quite amusing, but a bit of a grind... so 3 but leaning toward a 4....
 
I'm frigging Charlie Brown here... deal.

X-Men is the only one of those choices I actually own. And I've played it for all of a half hour.

So, probably none. Get Trenched instead.

I agree with everyone here who typed Trenched. 
Lara Croft is a good dungeon crawler from what I've heard over the past few months.  
Hard Corps I would suggest only if you like Contra. 
TMNT & Comic Jumper seem like rip offs to me from what I've read and heard from the reviews.
X-Men is kind of a rip-off since it's just a straight port of the quarter eater, so only get this if you have nostalgia from playing it back in the day. 
If I were you, and I'm not, I would use those points to get Trenched.  
There's your answer, get Trenched.         BOOYA!

Never did Lara in single player, but she's great fun together with a buddy.
