I don't get why people love Shelter so much, the characters just look weird to me, for all the "graphic enhancement" I much rather prefer the graphic this game has, or the artstyle whatever you want to call it. The other one is just ugly...
1. Irnia has 5 different artists. Saying it has a "style" is a stretch. The art looks all over the place.
2. Shrug. Well personally I disagree with you and think shelter art looks better. This is a matter of taste.
3. Shelter is not just graphics enhancement but also gameplay. Irnia has some questionable design decisions. (too many branches requiring too many replays... in a game about mind control). SHELTER simplifies it into only 2 routes, love (seduction) and mindbreak (typically via mind control). So you only need to play it twice.
well... regardless. starting a 3rd game with 2 unfinished ones doesn't look good.
